Abstract: A synchronous electric motor having a structure for reducing cogging torque generated by the positioning error of a permanent magnet. Protrusions are alternately arranged in regions A and B in the circumferential direction of an iron core. Therefore, with respect to neighboring magnets positioned on both sides of the first protrusion, in region B, where the protrusion does not exit, ends of the neighboring magnets are attracted to each other by magnetic force. On the other hand, with respect to the neighboring magnets positioned on both sides of the second protrusion, in region A, where the protrusion does not exit, ends of the neighboring magnets are attracted to each other by magnetic force resulting in being inclined in opposing directions, and thus the generated cogging torque is significantly reduced.

Abstract: An electric motor apparatus comprises a rotor and a stator formed of at least two stator components, each of the at least two stator components having a substantially hollow cylindrical form. The rotor is mounted within the at least two stator components on a rotational mounting such that the rotor can rotate about a longitudinal central axis with respect to the stator. Each of the at least two stator components has at least two protrusions arranged at different circumferential points on an inner surface of the at least two stator components. Each protrusion has a winding mounted thereon. Control circuitry generates control signals to control power supplied to the windings on each stator component such that power can be controlled to each stator component independently. The stator components are mounted adjacent to each other along the longitudinal central axis and rotationally offset with respect to each other such that the two protrusions on one of the stator components are offset with respect to the protrusions on an adjacently mounted stator component, such that a portion of each winding that extends beyond a longitudinal end of the protrusions on one of the stator components fits within a gap between windings mounted on the adjacently mounted stator component.

Abstract: In conventional rotors having a shape in which permanent magnets are skewed, a configuration in which, for example, the thicknesses of both ends of each magnet are increased is used in order to make the rotors symmetric between the forward and reverse directions, thereby causing excessive increase in the thicknesses.In a rotor 2 in which permanent magnets form magnet poles and the permanent magnets are skewed with respect to the axial direction, the thickness of each permanent magnet is increased at a portion that is most likely to be demagnetized, that is, a positive side portion F in a rotor part 2A skewed in the positive direction and a negative side portion F in a rotor part 2B skewed in the negative direction, whereby a demagnetization resistance strengthened portion is formed.
