A laundry appliance includes a drum rotationally positioned within a structural cabinet. An impeller is rotationally positioned within the drum. The impeller is selectively and independently operable with respect to the drum. A binary motor has a first motor and a second motor disposed within a common housing. A first drive belt extends between the first motor and the drum. A second drive belt extends between the second motor and the impeller. The first and second motors engage the first and second drive belts on a belt side of the common housing.

A method of manufacturing a magnetic pole piece includes molding a magnetic body having an outer wall and an inner wall extending between a first end and a second end, and a trim cap disposed at the first end. The method further includes fixing a non-magnetic isolator to the magnetic body between the outer wall and the inner wall and removing the trim cap.

A system and method for compensating for the changing power requirements of an electrical grid. A first generator is mechanically linked to a turbine and electrically linked to a power grid, such that the generator converts rotational energy into electrical energy to supply the power grid. The rotor of the generator is mechanically linked to the rotor of one or more additional generators, not connected to a turbine or the grid, via a continuously variable transmission. The turbine is maintained at optimal running speed. When the generator produces more electrical energy than required by the power grid, mechanical energy from the rotor is transmitted to the rotors of the additional generators. When the power grid requires more energy than generator produces, as the turbine runs at optimal efficiency, mechanical energy from the rotors of the additional generators is transmitted to the rotors of the first generator.
