If the rotating part of the motor winding is jammed, what happens to the windings?

When the rotating part of a motor winding is jammed, the windings experience a significant issue because they are unable to move as designed. This situation leads to excessive current flowing through the windings since the motor is trying to start but cannot. As a result, the electrical resistance in the windings generates heat.

This heat builds up rapidly because there is no movement to dissipate it or to convert electrical energy into mechanical energy. Continuous operation under these conditions can exceed the temperature limits of the insulation and materials in the windings. Consequently, this excessive heat can damage or destroy the windings, leading to coil burnout and failure of the motor.

Understanding the implications of a jammed motor is crucial for maintaining motor health, as regular monitoring and maintenance can prevent such destructive scenarios.
