    Causes of DC Motor Burnout

    1. The excitation current of the DC motor is too large. It depends on what method you use to power the excitation. Currently, the constant current method is used. If the voltage method is used for power supply, the current may increase with the increase of the grid voltage.

    2. The heat dissipation is not good, mainly because the cooling fan of the motor is broken.

    3. The insulation of the coil is not good, causing shorts between turns.
