Fan of the floor of the three.speed
The fan, like any other electrical device, has the ability to sometimes break, the stator winding most often burns in it. But this is not a reason to send him to retire. Within the framework of this article, let’s talk about the practice of repairing household fans.
We begin the process of disassembly by removing the fan cover, under it a single.phase dimensions with a short.closed rotor with a capacity of 20 watts are hidden under it. Let me remind you that the rotor is a moving part of the electric motor, which rotates due to. Thereby setting the blade of our fan.
The stator is a static winding that is located on the steel core of the electric motor. The stator transforms alternating current into a rotating magnetic field.
On external examination, of course, it is difficult to break off any device, if there are no obvious signs of damage to the speakers for themselves. In our example, we must call the stator winding and power cord for integrity. This is the easiest to do this using a regular multimeter, which should be in the instrumental arsenal of any radio amateur. About how to use the multimeter, you can find out.
After a series of measurements, it turned out that the supply cord is in perfect order, and the winding of the stator simply burned out at the household fan. With your own hands for repair, we will need to partially disassemble the engine. The stator winding can be easily removed with a regular screwdriver driving it with uniform blows, at the places indicated by the arrows in the photo.
After successful dismantling the stator winding, you can go to mathematics, namely, calculating the number of turns for the engine winding for the engine winding.
For the controlled calculation, you can take the following algorithm as a basis:
The voltage in the normal network of alternating current 220 volts, engine power. 20 watts, core cross section 1.2 cm 2. The current passing through the coil will be. 0.09 A. (based on the well.known formula I = p/u).
The cross.section of the typical wire can be calculated according to the following formula :
If we translate the cross.sectional area of the wire of 0.03 mm 2 to the wire diameter we get as a result: D = 0.19 mm
I borrow the wire from the coil of a magnetic starter with a diameter of 0.17 mm since I don’t know I can lay the right amount of turns on the reel frame.
In the latter case: U. network voltage, s C is the cross.section of the core, b C is the magnetic permeability of iron (maximum 14,000 ge).
As soon as we calculate the number of turns, you can start the winding. It is difficult to wrap around so many turns around the core, so I recommend using home.made.
After the coil is made, it is necessary to soak it with a special varnish for impregnation, otherwise the insulation of the wires in it may be disturbed.
After the varnish dries, it is necessary to install the coil back. If after assembly and verification there are problems with the direction of rotation of the blades, then you only need to remove the rotor and install it from another end core from another end. As an option, you can again pull out the stator coil, and turn it 180 degrees and install it back.
In the figure above the red arrows, short.closed turns are marked, the magnetic field that affects the rotor will concentrate on them.
In order to find the cause of the fan breakdown, it is necessary, as in the previous example, disassemble it. To do it is pretty simple. First, remove the protective grill, then pull out the blades or impeller, which is usually fixed with a special nut. Then it is necessary to dismantle the other part of the protective grate and unscrew the screws of the lid.
I also recommend that you study the typical scheme of the floor fan. It usually uses an asynchronous electric motor with 8 windings (working and launch). To successfully start the engine, it is necessary to create a phase shift by 90 degrees. For this, the circuit has a capacitor. The scheme will work after pressing the power button, while the indicator lamp should light up and the lobes begin to rotate, the engine rotation speed depends on the connection circuit, using the switch.
First you need to check the serviceability of the network wire. Then perform to launch a motor. It is also recommended to see the integrity of contacts and wires. If a hum or noise is heard during the fan, then you need to grease it with thick lubricant with a lithol.
The repair of the electric motor begins with the lubrication of the bearings, usually after that the fan begins to work well. You can use machine oil for lubrication.

A rather typical malfunction is a break in one of the stator windings. To check, you can sharply twist the blades in the direction of rotation of the clockwise. If the fan works, it has burned one of the windings.
The service life of the electric motor is reduced several times if you do not clean it from dust, and also if you forget to lubricate the bearings or gearboxes.
No matter how well the electrical engineering serves, sooner or later it fails. These devices that are operated very intensively break. They can be considered a household fan to them. Breakage in this product there are various. The owner has no choice but to contact the workshop. However, in some cases, you can do it on your own. To do this, it is quite good to know the device and the principle of operation of this electrical equipment. Information on how to carry out the repair of the fan with your own hands is presented in the article.

With how to turn on the heater correctly, we figured out. Now let’s look at several rules that should be accompanied by its operation. They must be observed in order to maintain both the performance of the device and the safety of all people living in the house or apartment. The rules are as follows:
- The parameters of the mains must correspond to the parameters of the heater. As a rule, the equipment is designed for 220 V, but just in case, this moment should be clarified by reading the instructions,
- Like any other device, an oil radiator needs periodic cleaning. Naturally, only the outer part of the device is cleaned, that is, its body. Before cleaning, be sure to turn off the equipment from the network to avoid getting a shock,
- If it is planned that the radiator will not be used for a long time, then it also needs to be disconnected from the network. However, this should be done with any electrical appliances,
- During the operation of the radiator, the power cord should not come into contact with the case (of course, the place of direct connection is not counted). Do not forget that the surface of the equipment is heated very strongly, so the cord braid with prolonged contact with it can melt or burn out,
- During operation, regularly inspect the device. If you notice any damage on its case or cord, you must immediately contact the repair workshop or purchase a new radiator. It is strictly not recommended to use the device with visible damage, since this can lead to a fire, injuries, and other difficult situations. The same goes for the performance of sensors, especially the temperature. If it is broken, then you can not use the device until the replacement of the failed element, since you cannot notice overheating yourself, and this will lead to a breakdown of equipment,
- Another ban on the placement of various objects on the oil heater. For example, it is impossible to dry clothes, bedding and other textiles on it. You also do not need to close the radiator with decorative panels and mask it with other methods. All this can lead to overheating and, as a result, to the breakdown of equipment. If the drying of clothes on the heater is an extreme necessity, then choose a model with an attached dryer. On the radiator itself, it is strictly impossible to throw fabric,
- If your heater refers to a mobile variety. that is, it can be moved from place to place thanks to the wheels available on the lower panel. in no case do not move it behind the food wire, since this can lead to a cord break and, as a result, to a short circuit,
- When placing the device, pay attention to its remoteness from the walls. If the distance from them is less than half a meter, then the radiator will constantly overheat and turn off, so he needs a slightly more extensive space.
How to assemble a floor fan Tefal
And you knew that there are fans that also protect from mosquitoes? Tefal with a combined system for supplying fresh air and spraying a product from mosquitoes. My salvation in summer heat
Now I wish you to tell you about the floor fan Essential (Mosquito) Protect VF4210 from Tefal.
The floor fan Tefal VF4210F0 will create a cool breeze and will not let the air stagnate.
Three speeds of work will allow you to choose the most comfortable option: from light blowing to a powerful stream (up to 55 cubic meters.m/h). Settings are set by a mechanical swivel regulator.
There is a special slot above the control panel where you can insert any standard bottle of fumigator liquid. Thus, the fan not only refreshes the air, but also sprays the liquid from insects throughout the room.
The fan is packed in a large box of cardboard, which turned out to be quite heavy by weight. You can bring a girl to a girl, but only if carefully.
On the basis of a little information about this fan model. The main characteristics and advantages are painted.
In fact, there is not very much information, but it is provided in several languages at once.
It seemed to me not very convenient that the box is not equipped with any handle.
Inside everything was composed very tightly, so even when turning the box. did not shake and did not thunder.
Review of the floor fan Tefal VF4210F0
The fan is sold in a disassembled form, so you will have to collect it yourself. Each element is neatly packed in protective material, only the blades were without everything.
The first, and probably the most difficult part. Foot stand.
She was packed in a plastic bag.
Inside which there were additional details for assembly. I liked that all sorts of screws and screws immediately went at the same time with those details where they had to be screwed.
The stand weighs decently, thanks to this the fan is stable even at maximum speed.
At first I did not quite understand why the stand is so dirty. But wiping it with a rag, she found that it was a plastic of such an interesting color in itself.
Outwardly the stand is made of white plastic. External rim. glossy, and inner circle. matte.
Next comes the leg. She is firmly packed in cardboard.
And also in film, so that nothing gets scratched.
It is not very heavy, although it is made of metal. Visually, it is glossy and smooth. It is sold short, but its length can be adjusted at your discretion. The maximum fan height. 140 cm.
The next is the basis, which, like all other details, is carefully packed in protective material.
Probably, it is stronger than all, since he was at first in cardboard and foam, and then. in the package.
The cord is also wrapped in a film, and inside is still tumored with wire. Its length. 1.5 meters.
The basis, from which, in principle, the fan works is also quite weighty.
Looks like a device for checking the speed of machines.
A head of glossy black plastic is strung on the base.
Behind there is a small sticker with the power of the device and the brand logo.
On the basis there is a compartment, thanks to which this fan model and differs from all others. Antimoscate function.
The cover is very tight, I almost broke a couple of nails for myself until I opened it for the first time. Then I realized that it was better to use fingertips.
You can screw any liquid from insects into the compartment, and click on the button with the inscription Protect when operating the fan, and the air flow will begin to spread the liquid throughout the room.
They are made of durable transparent plastic of blue shade.
They are not very wide, which allows them to spin easily and quickly.
Details of the body protecting the screw were in the same packaging.
There was some incomprehensible and unnecessary piece of paper inside.
The case consists of 2 parts of the same shape. They lie in each other, and there are a couple of paper sheets between them.
The upper half has a logo located on a plastic circle, as well as an external rim.
The back panel is completely metal.
When assembly, the base is quite voluminous.
Air easily passes through a small mesh, but it also protects well from a spinning screw.
As I wrote earlier, the fan is sold in a disassembled state. The assembly is basically easy, it will not take much time if you first study the instructions. I managed in 20 minutes.
The instructions have options for assemblies of several models at once, so look for yours by number. My one that is presented on the left side.
First you need to assemble the lower part of the fan.
Next comes the upper part with a spinning mechanism.
It must be placed in an open part of the stand.
Previously, it is necessary to unscrew the screw inside, otherwise the stick itself will not stand tight and will fly out.
It is removed using a special mechanism.
If desired, you can immediately adjust the height of the finished fan.
From the base, twisting the screws, you will need to unscrew a couple of details.
It is easy to do this, since there are instructions on which direction you need to turn.
They are unscrewed quickly and without problems.
No keys and screwdrivers, everything is done with your hands.
TEFAL Essential fan 
The pin on which it is necessary to string parts of the base and blades appears to us.
Then it is twisted by a little thing, which we unscrewed the second. Make sure that everything is tightly screwed and does not hang out, since you do not want a part of the fan with working blades, God forbid?!
Overview for Fan Faller Zanussi ZFF-705
We consulted with colleagues and decided to buy a fan to the office, the choice is huge in the market, but I did not want to take it very cheap.
Chose relatively non.expensive, within 2 thousand, so that there was a powerful enough (
45 watts or more), not very low (almost all a meter in height), the stand would be round and not in the form of a cross, since on a cross for such money they cost very uncertainly, well, so that it looks worthy.
I chose as always on online.ru, never let me down!
Of the suitable ones, several Ballu and Zanussi were suitable for our criteria, but the former had some kind of problem with the presence, so it was decided to take Zanussi ZFF-705, there were no reviews of it, they took at their own peril and risk.
The order came the next day, as always thanks online.ru for operational delivery and that they did not allow to die from the heat.
Came disassembled, in a dense cardboard cow, beautifully decorated.
For assembly you only need a thicket of a protective grid to tighten.
It looks very bad. The stand is heavy, it stands confident on it, the right choice.
The power is an excellent fan, at 3 speeds blowing off in the office everything that is poorly held on tables and walls (documents, calendars).
The noise is quite quiet, only the wind is heard.
The buttons are decent, require confident pressing with pressing until the end.
The height is adjustable using a special steeple.
There is one claim to painting a protective grid.
In one place was painted as if on a piece of whitewashing or other powder.like and when assembly, the paint took off safely.
I took a picture after tinted with a black marker, now it is not striking. Not critical.
The fan can be adjusted up and the rotary mechanism works, below the video example of work
As a result, I can recommend this fan for buying, he fully justified my requirements and expectations.
Review: floor fan Zanussi ZFF-907-without a fan at home in the summer.
I want to share with you my impressions of the Fleet Fan Zanussi ZFF-907, which we recently purchased on our favorite “berry” site when our good old one, who has been serving for almost 9 years, just scattered into pieces. Therefore, they urgently began to look for something budget-not to die in the heat of the house (we also have the sunny side).
Here, on an echo, I did not find reviews, and those that are written on the site itself. the frightening ones were interspersed with the enthusiastic. I decided to tell in order about our purchase exactly here. so that it was clear before placing an order that you are buying.We paid 1899 for the fan (ordinary. specially compared in ordinary city stores).He came in such a box.
The main information about the product is provided on the box.
In fact, what you need to know before buying: the fan has no legs, instead of it a round (rather heavy) base, mechanical control. 4 buttons: three speeds and a shutdown button, its weight is 4.5 kg and it is quite bad in operation. This is in short.In this form there was a fan inside the box. since it is new, of course, disassembled.
Here is such a base, we took off the film, it shone directly. Only now the dust is easily sitting on him.
Blades and protective grilles were in a separate package. Everything came whole and unharmed.
And of course, the instructions for use was inside the box.
My husband and I were struck by the blades-firstly, they are transparent.
Secondly, for some reason a feeling of fragility is created-but perhaps this is precisely due to transparent material.
This is what it looks in the collected form. Very stylish, in my opinion, is suitable for any interior.
This is what the control panel looks like. ordinary buttons, but you can quite quietly switch them. tried already while the children were sleeping, and it was necessary to put the first at the first at night. Quite convenient.
The protective grill is quite small, which is convenient in a house with young children. it is more difficult to put your fingers there. Not that impossible, but still.
As for the work. here we were satisfied. The fan is powerful, the air distiliates well. At the third speed, of course, it works noisily, in the sense that it is heard, but this is such a pleasant rustling. Yes, and we usually put on the second speed, and at night we switch to the first. this is quite enough. At the first speed, the fan works almost silently, almost like a light breath of wind.
Search and elimination of malfunctions during the repair of a household fan
Before proceeding with your own hands, it is necessary to study the scheme of the device. As a rule, an asynchronous electric motor is placed in the floor fan, consisting of eight windings (working and starting). For a successful launch, a phase shift is required by 90 degrees. For these purposes, the capacitor is installed. The device begins to work after pressing the turning button, after which the indication light lights up and the engine starts, the rotation speed depends on the switch of the windings, for which the switch 3 of the speeds with mechanical locking of the simultaneous turning on several buttons, in which short circuits may occur, is possible.
Before proceeding to check the electric motor:
- Immediately you need to check the serviceability of the connection cord to the electrical outlet. To do this, you must first disassemble the switch block, and then, in compliance with electrical safety measures, check the presence of 220 volts on the contacts of the light bulb with a multimeter.
- Check the serviceability of the capacitor according to this instruction.
- Call integrity and check the reliability of all contacts of wires and connections in the circuit. Barling instructions.
- If a rumble or noise is heard during the fan, then lubricate the plastic parts inside the gearbox with a lithol or solidol through the holes, which are specifically provided for in it.
- Check the presence of 220 volts at the output from the switch button on.
Online calculation of the capacitor of the motor condenser
Enter data for calculating the capacitors. engine power and its efficiency
There is a special formula by which you can calculate the required container for sure, but it is quite possible to do with an online calculator or recommendations that are bred on the basis of many experiments:
The working capacitor is taken at the rate of 0.8 μF per 1 kW of engine power; The launch is selected 2-3 times more.
Capacitors should be non.polar, that is, not electrolytic. The operating voltage of these capacitors should be at least 1.5 times higher than the network voltage, that is, for the 220 V network, take capacities with an operating voltage of 350 V and above. And to make the start passes easier, look for a special capacitor to the starting circuit. They have the words Start or Starting in the marking.
