| description | A motor control (34) for an exercise treadmill having an AC motor (38) includes various features to enhance operation of the treadmill. These features include a motor control (34) that can vary by shifting or staggering the phases of drive signals applied to the motor (38) in order to reduce treadmill frame vibration. The features also include having a motor controller (36) increase the slip of the motor (38) to improve low speed operation of the motor (38) and to increase the amperage of the drive signals when the motor (38) is operating at a given speed in order to maintain that speed. In addition, a power factor control circuit (52) can be used to increase the efficiency of the motor (38). |
