Abnormal behaviour: motor of the treadmill accelerates and decelerates - solved

In this first video we show the strange behavior of the treadmill. After replacing the broken controller with a new one, we can see that the engine accelerates and decelerates suddenly.


In this video, we show how to check the motor status by means of an amperometric clamp. As you can see the current consumption oscillates. This is a clear symptom that the motor is demagnetized and absorbs too much current.


In this last video, we show the light bulb test performed on the treadmill. As you can see, the card adjusts the voltage to the light bulb, that changes its light intensity, according to the speed of the treadmill. This shows that the controller works correctly, and the defect is due to the demagnetized treadmill motor.
