Q:What is the maximum speed of a three-phase AC motor?
This motor is divided into pole number, 2 pole motor synchronous speed 3000RPM; 4 pole motor synchronous speed 1500RPM; go down and so on
Q:How to distinguish between DC motor and AC motor?
As communication is easier to obtain and easier to carry, so most of the electric machines we use today are driven by AC motors.
Q:What is the reason that the single phase AC motor is turned on and off?
Exclusive use only. Check the switch first, is there any bad contact?. After the problem of the switch is removed, the power is turned on, and whether the cold state can run normally every time. If there is a phenomenon that the cold condition can not work properly, the internal circuit or winding is not working. If the cold running is normal and the use of a period of time does not turn, and then use the hand to touch the motor whether the fever is serious, such as temperature is too high, the heat protector is broken, and so the motor can be turned cold. This phenomenon should check whether the no-load and load resistance of the motor is too large, whether or not the winding has a short turn between the two places, causing the temperature rise too high.The two capacitors on the motor, one is the starting capacitor, the other is the operating capacitor, which produces phase difference. The starting capacitor is only connected to the circuit when the motor is started, and it is disconnected when it is running normally. The operating capacitor is always connected to the circuit.
Q:AC motor stator winding does not turn, why the back EMF?
According to the electromagnetic law, when the magnetic field changes, the nearby conductor will produce an induced electromotive force, which is in accordance with Faraday's law and Lenz's law, and the original voltage at the opposite end of the coil is reversed. This voltage is the back electromotive force.
Q:Motor starting mode
Starting with buck transformerThe autotransformer start voltage, the starting current and starting torque of the motor and the end is proportional to the square of the lower, to obtain a large starting current to start the same situation. Such as starting voltage to 65% rated voltage, the starting current is full voltage starting current starting torque is 42%, full voltage starting torque 42%.The advantages of self coupling transformer step-down start is the direct manual control, automatic control can also be used for AC contactor, durable, low maintenance cost, suitable for all the no-load and light load start using asynchronous motor, is widely used in the production practice. The disadvantage is the manual operation to transformer box configuration more expensive (from I), automatic control box compensator to configure auto transformer, AC contactor start-up equipment and components.
Q:AC motor control chip
This motor is single-phase or three-phase, ah, second power, how big, these need to know.If it is a small single-phase or three-phase motor, AC motor can be controlled by solid-state relay or by small AC contactor control relay, if it is large, it is best to use the second scheme just said. It is so simple. What if there are special requirements that is another, I can talk.
Q:Main structure of AC motor
The core is: the magnetic circuit of the motor, the iron core is fixed on the frame, a silicon steel sheet surface insulation Die pressing, punching a uniform circular notch of silicon steel sheet, for stator winding. Stator winding: the circuit part of an electric motor.
Q:How to judge the quality of three-phase AC motor?
Measuring U1, U2, W1W2, V1, V2 by means of an ohmmeter is conducted. If the barrier is not good, it is better to measure the resistance of the earth with a ohmmeter
Q:What is AC motor?
AC motors are divided into two major categories: synchronous motor and asynchronous motor. The rotor speed of synchronous motor ns is the same as that of rotating magnetic field. It is called synchronous speed. There is a strict relationship between ns and the frequency of the AC current (f) and the magnetic pole logarithm (P) of the motor. Ns = f/P in china,The power supply frequency is 50 Hz, so the synchronous speed of the dipole motor is 3000 revolutions per minute, and the synchronous speed of the quadrupole motor is 1500 revolutions per minute. The rotor speed of an induction motor is always lower than or higher than the speed of its rotating magnetic field, and the asynchronous name comes from it. The difference between the rotor speed of a induction motor and the rotating speed of a rotating magnetic field (referred to as slip) is usually less than 10%. It can be seen that the speed of AC motor (synchronous or asynchronous) is controlled by the frequency of power supply. Therefore, AC motor speed is difficult, the best way is to change the frequency of power supply, and in the past to change the frequency of power supply is more complex. Therefore, before 70s, in the speed control occasions, the use of DC motors. With the development of power electronic technology, AC motor frequency conversion speed regulation technology has begun to be practical.
Q:What are the similarities and differences between brushless DC motor and AC brushless motor?
Brushless DC (brushless, DC, BLDC) and brushless BLAC (brushless AC) (this name does not seem to be used in Chinese) are all permanent magnet synchronous motors. The two motors do not depend on the waveform of armature current and back emf. If the back EMF and armature current are rectangular waves, that is BLDC, and if it is sine wave, that is BLAC. Of course, the back EMF is rectangular, and also sinusoidal current, which becomes the BLAC operating mode, so the waveform of the current is still to be seen.
