How to use battery electric locomotive traction motor safely?

The traction motor is a core component of the mine battery electric locomotive, which is mainly used to provide power for the electric locomotive. Safe and correct use can reduce the occurrence of failures and improve production efficiency. Then, what should we pay attention to in use?
1. According to the characteristics of the motor, when passing the unloading station, the electric locomotive must be powered off and pass by running inertia. Forced power off is strictly prohibited, otherwise the motor will be severely damaged.
2. Reverse connection braking is not allowed. In the design of battery electric locomotives, electrical braking is generally not used. When the heavy-duty electric locomotive runs downhill by its inertia, the electric motor cannot be used to reverse and stop. At this time, the motor has become the operating state of the generator, and the electric brake is forced, the current of the motor armature winding will increase exponentially, causing the motor to overheat, resulting in damage to the insulation of the armature winding and the magnetic pole winding, and ring fire on the commutator, and the motor damaged severely. In addition, other electrical equipment and mechanical parts will be severely damaged.
The above are some of the things that should be paid attention to when using the traction motor of the mine electric locomotive.
