During the rotation of the rotor, the permanent magnet and the armature cogging structure inside the motor create a tangential force that interacts with each other. The torque generated by this tangential force will attempt to align the permanent magnet poles of the PMSM with the cogging centerline. In the event of a loss of power in the system, this tangential force remains, and the cogging torque is the moment generated by this tangential force.
