Как да използвате a мултицет да измервате окабеляване метод на на климатик вътрешен вентилатор
Вътрешни вентилатори на домакинство фиксирана честота климатици общо взето употреба еднофазни AC двигатели до задвижване охлаждане% 2fheat обмен на вътрешен въздух климатици или изпарители. Входът напрежение е 220V от мрежата 2c и мощността е между 15 и 25W. Неговата мощност е конфигуриран според размера на климатик модел.
In order to provide large, medium and small air volumes, it adjusts the speed by tapping in the coil winding. The high, medium and low speeds of fixed-frequency air conditioners are most controlled separately by three miniature DC relays, which are programmed in the electronic board to instruct the actions of each one. But their control output voltage is all 220V. The speed of the fan is regulated by the coils свързан в серия вътре двигателя.
Това метод е да подходящо вграждане на скорост регулиране намотки в статора ядро слотове на на мотор. Тези скорост регулиране намотки може да бъде в същото слот като на основните намотки. Дали това е в на същото слот като на основната намотка или в на същото слот като на спомагателни намотка , на скорост регулиране намотка е винаги на горната слой на слота. Работещият принцип на това вид на мотор е по същество да промени силата на статора магнитно поле и елиптичността на статора магнитно поле да постигне целта на промяната двигателя скоростта.
This kind of motor has five wires, among which the white one is the common wire, which is connected to the capacitor with the yellow wire. The A winding coil is the main winding coil, in which there are two groups of black ~ gray, gray ~ red coil windings connected in series, and the red ~ yellow winding coils are The secondary winding coil, capacitor is always connected with the yellow wire. When the white ~ black wires are connected to the 220V power supply, the fan is at high speed; when the white ~ gray wires are connected to the 220V power supply, the motor speed is medium speed; when the white ~ red wires are connected to the 220V power supply, it is Run at low speed. There are too many brands of air conditioner indoor fans, and their colors are also different. If the wiring diagram cannot be seen on the label of the fan, you need to use a multimeter to set the R×1 position. When measuring the fans, use the resistance value comparison method to measure them. resistance value between. Because they are all connected in series, based on one line, measure it with the other four lines. If you measure the largest resistance value between them, it means that the two lines at this time are the lines connected to the capacitor. One of them must be a common line. At this time, you can assume that one of them is a common line, and then use the resistance level to measure its resistance value. The resistance value of the running winding is smaller than the resistance value of the secondary winding coil. At this time, the running winding can be determined. In fact, the resistance values between high, medium and low are smaller than the resistance values of the main winding coil and the secondary winding coil. Following the clue, the resistance value at the higher end of the secondary winding is the medium speed wire, and the resistance value at the end of the secondary winding is larger. For the low speed gear wire.
