Abstract
A fabric washing machine includes a container to receive fluid and fabrics to be washed in the fluid. A switched reluctance motor includes a stator and a rotor directly connected to the container so that the rotor and container oscillate together to wash the fabrics and continuously rotate together to extract fluid from the fabrics. A control stores a plurality of sets of empirically determined wash values representing instantaneous rotor velocities, calls up individual values in a predetermined timed sequence and controls the motor in accordance with the currently called up value to provide oscillation of the rotor and container. User operable means selects which set of wash values is used in a particular wash operation. The control also stores a set of empirically determined spin values representing instantaneous rotor velocities. User operable means selects at least one spin value representing a rotor velocity less than the maximum velocity represented by any stored spin value. The control calls up spin values from the stored set of spin values, compares the called up value with the user selected value and controls the extraction operation in accordance with the compared value representing the lower velocity.
