I remember helping a friend to get his treadmill working again after the motor burned out. It was an old machine made by 'York' and we managed to buy the very last replacement motor of its type in the UK, think it was about £100. They are powerful motors! We had to replace the SCR and the FET which controlled it and that got it going again. We never had a circuit for it, so not sure how it was controlled.
