Axial flux permanent magnet motor is an electric motor having high attractive force between the rotor and stator. The force causes stress and wearing to the supporting structures in the motor and in the device to where the motor has been installed to. After certain period of time these stresses and wearing can cause the air gap between the rotor and stator to be decreased and in the end it will close completely. The closure during operation of the motor will cause mechanical contact and damage to the motor. The decreased air gap between the rotor and stator can be detected from a change in the electromotive force voltage between the rotor and stator. When the change is detected the operation of the motor may be stopped and the defect can be repaired before further damage is caused.
