What are the reasons for the overcurrent of mining electric locomotive traction motor?
The overcurrent of mining electric locomotive traction motor is generally mainly due to overload, followed by short circuit of the coil or aging of parts.
There are two main reasons for overload: one is overload, that is, the electric locomotive pulls too many mine cars at one time, resulting in excessive pressure on the motor. In addition, the dual-motor electric locomotive has a problem with one motor and "strikes", and one motor undertakes the work of two motors. At this time, although the electric locomotive may not be overloaded, the motor is in an overloaded state. The solution is not to overload, and check the motors daily to ensure that both motors can work.
Other problems can be regarded as a kind of problem, that is, component damage. The short circuit of the coil is generally also due to the damage of the insulation layer, especially for other parts. So just replace it. You can usually pay more attention to fasteners, etc., and carefully check each component during regular maintenance.
The above are the reasons and solutions for the overcurrent of mining electric locomotive traction motor.
