Abstract: An electric motor, of the type that includes a rotor with permanent magnets and a stator with electromagnets, which operates at high efficiency to produce a high ratio of mechanical power output to electrical power input. During rotor rotation in a first direction (74, FIG. 5), a first magnet (44A') moves away from a position of alignment with the core of a "last" electromagnet (46A), while a second permanent magnet (44B') moves toward a position of alignment with the core of a "next" electromagnet (46C) which it is approaching. The last electromagnet (46A) is energized in a direction to negate attraction of its core (50) for the first permanent magnet (44A'). The next electromagnet (46C) is not substantially energized, so the attraction of the second magnet for the next electromagnet (46C) is due primarily to attraction of their cores in the absence of energization of the next electromagnet.
