Causes of burnout of the motor of the mine spraying machine:
1. Overload. If the protection function is normal (installed thermal relay), it will not happen generally.
2. Internal reasons of the motor of the mine spraying machine, due to bearing damage, wear of the end cover, wear of the main shaft, sweeping of the rotor, and damage and burning of the wire package are also the main reasons.
Others: such as the voltage of the mine hydraulic support is too low or too high, the vibration causes the terminal to loosen and short-circuit between phases, insects and rodents harm, the voltage of the imported mine spraying machine motor does not match the domestic voltage (such as the mine spraying machine motor). Various decompression starting circuit failures cause non-conversion, the mine spraying machine motor works at low voltage for a long time, etc.
