Causes and Measures of Special Motor Failing to Start

The reason:
1. The cable diameter is too thin and the wiring is too long, causing the line voltage drop to be large, the voltage is low, the axial magnetic tension is reduced, the brake spring can not be opened, and the motor is in the state of blocking rotation.
2. The brake ring is swollen by water and dampness, and the hoop is tight on the corroded moving surface, which produces adhesion and can not be removed from the braking state.
3. Blindly adjust the lock nut, adjust it to the limit, and the lock is locked in the braking state.
4. The axial channeling part between the motor and the reducer is stuck or rust dead, and can not channeling, and the motor is locked in the braking blocking state.

Measures:
1. Thicken the cable to reduce the line voltage drop.
2. Remove the fan brake and clean the adhesive corrosion surface.
3. Readjust the lock nut according to the rules.
