Abstract
A fabric washing machine includes a container to receive fabrics and fluid to wash the fabrics. A switched reluctance motor is operatively connected to oscillate and rotate the container. A control operates the machine by providing commutation signals to the motor to energize the stator phases in a predetermined sequence as corresponding rotor phases approach the stator phase being energized. To stop the machine the control repeatedly senses the instantaneous alignment of the stator and rotor phases and supplies commutation signals to the motor to energize the stator phases in the same sequence but as corresponding rotor phases have become aligned with the stator phase being energized.
