The reason why Watson's high-speed mixer keeps heating but does not rotate: 1. If the motor is damaged, replace it directly according to the original motor model and category, such as DC motor or AC motor. 2. If the fuse tube of the series motor is damaged, it can be replaced according to the original specifications. 3. If the thyristor of the motor drive voltage control tube is damaged, it should be replaced according to the original model and power. Never replace components with too different parameters.

It may also be that the AC motor power relay is damaged, the relay coil is broken or the contact is ablated, so it can be replaced directly to ensure normal power supply.
