An AC motor is an alternating current motor, and a DC motor is mainly a direct current motor.AC is alternating current: AC for short. Generally refers to the voltage or current whose magnitude and direction change periodically with time. Its most basic form is sinusoidal current. The standard frequency of AC power supply in my country is 50 Hz. Alternating current can take many forms over time. Different forms of alternating current have different applications and effects.DC is direct current: a

1. Fault phenomenon: the servo reports an error OL, the servo motor cannot be started, and there is abnormal sound fault analysis and possible causes:(1) Bearing damage, foreign objects falling and stuck, stator magnet bursting and falling off, or moving mechanism stuck, etc., are caused by the motor itself.(2) The external causes of the motor include: phase loss operation, failure of the starting equipment, and severe overload of the motor.2. Fault phenomenon: After the servo motor is started,

During the application of the servo reducer, due to the influence of various factors, the fatigue pitting corrosion of the servo reducer cannot be prevented. Fatigue has pitting corrosion, which is smaller and shallower in diameter at the beginning, and many occur in and under seams. After the onset of fatigue pitting corrosion, the speed of development is very fast. If we don't find it in time, a lot of gears will be scattered. As a result, the gear will be scrapped, and the servo reducer c

Induction motor is also known as asynchronous motor, that is, the rotor is placed in a rotating magnetic field, and under the action of the rotating magnetic field, a rotational torque is obtained, so the rotor rotates. The rotor is a rotatable conductor, usually in the shape of a squirrel cage. The stator is the non-rotating part of the motor and its main task is to generate a rotating magnetic field. The rotating magnetic field is not achieved mechanically. Instead, alternating current is pass
