Power supply problems, such as fuse blowing, circuit breaker damage, control circuit failure, contactor failure or contactor damage. Problems of the motor itself, such as short circuit between coils, grounding, bearing stuck, rotor broken, etc. , causing the motor to overload or even fail to start.

When it is found that the motor does not turn after the power supply is put into use, it is necessary to disconnect the power supply first, then check and turn the rotor with tools or hands to see if it can turn. If it can rotate, it means that the mechanical load and the motor itself are not stuck.

As an important part of automobile, the quality of motor will seriously affect the performance of automobile. Therefore, for users, if the motor does not turn, it needs to be solved at the first time, and it is best to go to the repair shop for repair.

Matters needing attention in the use of motor

1, the metal shell of electric agricultural machinery must have reliable grounding device or temporary grounding device to avoid electric shock accidents.

2, the power supply line of electric agricultural machinery must be installed in accordance with the rules of electricity consumption, it is strictly prohibited to pull and connect.

3. When moving electric agricultural machinery, be sure to turn off the power supply in advance and never move with electricity.

4, the use of single-phase motor agricultural machinery, to install low-voltage electric shock protector, and often keep it sensitive and reliable.

5, electric agricultural machinery failure must be power outage maintenance, can't live work.

6, agricultural machinery operators should enhance safety awareness, strict implementation of operating procedures. Wear insulated shoes when operating, do not wipe electrical equipment with hands and wet cloth, and do not hang clothes on wires.

7, long-term unused or damp agricultural machinery and tools, should be put into normal operation before commissioning. If it doesn't work after being electrified, it must be powered off immediately for maintenance.

8. In case of electrical fire, cut off the power immediately, and don't splash water on the fire before cutting off the power to prevent power transmission and leakage. If someone gets an electric shock, cut off the power immediately before saving people.
