ABSTRACT:
Improvements are described in an electric motor that includes a rotor with permanent magnets and a stator with electromagnets, of the "release" type wherein current to a "last" electromagnet that a permanent magnet is moving away from, receives only enough current to "release" the permanent magnet from the electromagnet core, with the permanent magnet attracted to the core of the "next" electromagnet whose coil does not carry current. The amount of current to the "last" electromagnet varies with the angular distance of the permanent magnet moving away from the "last" electromagnet. The electromagnets and permanent magnets can be in a ratio of 3 to 2. The percent of total electromagnets which are energized during each complete rotation of the rotor, can be reduced to save electricity when only a small output torque is required.
