Q:What are the stator and rotor functions of an alternating current motor?
If it is a three-phase AC motor, the stator generates a rotating magnetic field to drive the rotor. If it is a single-phase AC motor, the stator generates an alternating magnetic field with a magnetic field phase difference of 90 degrees to drive the rotor. The action of the rotor is that, in the case of an asynchronous motor, it produces an electric current in the stator rotating magnetic field. According to the principle of the right-hand rule, it will operate in the direction of the rotating magnetic field at a speed less than the rotation of the rotating magnetic field. And the mechanical energy generated is transmitted to the dragging device.
Q:The difference between synchronous motor and asynchronous motor
The synchronous motor belongs to an alternating current motor, and the stator winding is the same as the asynchronous motor. Its rotor speed is the same as that of the rotating magnetic field generated by the stator winding, so it is called synchronous motor. Because of this, the phase of the synchronous motor is ahead of the voltage in phase, that is, the synchronous motor is a capacitive load. To this end, in many cases, synchronous motors are used to improve the power factor of the power supply system.
Q:What is the principle of the single-phase AC motor in the washing machine?
Single-phase AC motor principle: with single-phase capacitor type motor: single-phase motor has two windings, namely starting winding and running winding. The two windings are 90 degrees apart in space. A capacitor with large capacity is connected in series on the starting windingWhen the running winding and the starting winding pass through the single-phase alternating current, the current in the starting winding is 90 times higher than the current of the running winding in time by the action of the capacitor, and the maximum value is reached first. Two of the same pulse magnetic field is formed in time and space, so that a rotating magnetic field produces the air gap between the stator and the rotor, the rotating magnetic field, the induced current in the rotor current, and rotating magnetic field interact to produce electromagnetic torque, the motor rotation.
Q:Structure of alternating current motor
AC motor consists of stator and rotor, and the stator and rotor is using the same power, so the current of stator and rotor in the direction of change is synchronous, i.e. the current direction in the coil is changed, and the direction of the current in the electromagnet, according to the left-hand rule by magnetic coil coil can continue to turn the direction. Go on.
Q:What does the D axis and the Q axis mean for AC induction motors?
The motor rotor has established a coordinate system, the coordinate system and the rotor synchronous rotation, the rotor magnetic field direction as d axis, perpendicular to the rotor magnetic field direction as q axis, the mathematical model of the motor will be converted into coordinates, can realize the decoupling of d axis and q axis, so as to obtain good control characteristics.
Q:Winding of single-phase AC motor?
Single motor is divided into main winding, secondary winding, main winding is working, and negative winding is started. The three motors are divided into main and secondary windings, and the three sets of coils are all working.
Q:What is the maximum speed of a three-phase AC motor?
The maximum speed of the three-phase AC motor is determined by the power supply frequency and the number of poles of the motor. The maximum synchronous speed is =60*, frequency (50) / magnetic pole number (1), =3000 rpm, and the asynchronous speed is about more than 2900 revolutions per minute.
Q:How to choose the AC motor?
The motor is nothing more than the source of mechanical power and speed. The speed and power required for the operation of the equipment can be calculated and the model can be selected.
Q:Can AC motors use direct current?
AC motors use direct current, because the motor will not rotate, it will burn the coil in a short time.
Q:AC motor: use gear variable or frequency conversion?
The advantages of variable frequency speed control is that a wide range of stepless speed regulation can be achieved within a range of any speed, at the time of transmission, the motor does not need to stop. Now the price of converter is not very high. But there are disadvantages, the reliability of electronic products is much worse than the reliability of mechanical products, even the normal operation is also prone to problems. And when there is a problem that the speed of the speed in the rated speed is a constant torque speed regulation process, that is to say its speed down, while torque did not change, the output power is motor becomes small. The device will not work on certain load characteristics. At this time, it is necessary to use the gear change structure to speed down at a high speed, then decelerate under the gear change mechanism to obtain large power.
