First identify the two ends of the three-phase winding.

Continuous operation of three-phase asynchronous motor, daily maintenance content: appearance inspection

The winding should be dried first if it is grounded by moisture, and when it is cooled to about 60-70 °C, it is poured with insulating paint and then dried.

Observation method. By visually inspecting the winding end and the insulator in the trunking, observe whether there are traces of damage and charring, and if so, it is the groundin

The three-phase asynchronous motor consists of two basic parts, a fixed stator and a rotating rotor

The motor should generally be equipped with fault protection devices, such as thermal protection devices, motor electronic protectors, etc.

Compared with single-phase asynchronous motors, three-phase asynchronous motors have good running performance and can save various materials.
