ABSTRACT:
A dual motor has a shaft and a first motor connected to the shaft. The first motor is a standard electrical motor receiving voltage steps. The first motor provides a rotational force to the shaft when the voltage is applied. A second motor is also connected to the shaft, and the second motor is a permanent magnet motor comprising a flexible member connected to the shaft at a flexible member inside end. The permanent magnet motor also has an inside magnet mounted to a flexible member outside end, and the inside magnet moves relative to the shaft. The permanent magnet motor also has an outside housing. An outside magnet is mounted to the outside housing, and stepped voltage application flexes the flexible member. Optionally, stepped voltage application flexes the flexible member so that the outside magnet rotates relative to the inside magnet.
