When the ac servo motor is turned off, the rotor shaft is tight

When the ac servo motor is out of power, the shaft of the rotor shaft is very tight: Since the servo motor is the brake device, the motor is not moving when the power is off. If there is no brake device, it indicates that the load is not installed properly, which can cause rotational difficulty. Solution: loosen the load and turn the motor separately.

If there is no brake device, it indicates that the load is not installed properly, which can cause rotational difficulty. Solution: loosen the load and turn the motor separately. The structure of ac servo motor can be divided into two parts, the stator part and the rotor part. The structure of the stator is basically the same as the stator of the rotating transformer, and in the stator iron core, there is also a two-phase winding of the Angle of 90 degree Angle. One group is the excitation winding, the other is the control winding, the ac servo motor is a two-phase ac motor. When ac servo motor is used, the excitation voltage Uf is applied at both ends of the excitation winding, and the control voltage is applied on both ends of the winding winding. When the stator winding is combined with the voltage, the servo motor will soon turn. Going into the field winding and control winding current to produce a rotating magnetic field in the motor, the rotating magnetic field to determine the steering motor, when any one of favorite on winding voltage inverting, the direction of the rotating magnetic field is changed, the direction of the motor is also changing.

It is necessary to make sure that the servo motor is equipped with the brake device. If there is a brake, the motor will not move when the power is off. If there is no brake, the servo motor should be a free state, and the axis of rotation should be very light, and the axis of rotation can be turned by hand. The load is not well installed, causing the difficulty of turning, releasing the load, turning the motor independently, and confirming the problem by turning the load independently.
