Abstract: In a motor stator, teeth radially project from an annular stator core, and a plurality of slots formed between adjacent teeth are skewed. Phase windings alternately pass through slots having different skew directions, wherein the length of bridging portions, which do not contribute to generation of torque, is short and the length of the portions which are located in the slots, and which contribute to the generation of torque, is long. Further, the phase windings are bent at an obtuse angle at opposite ends of the bridging portions.

Abstract: A rotary electric motor has a stator with a plurality of axially spaced sets of corresponding stator and rotor elements. The stator of each set is an annular ring with poles circumferentially positioned about an axis of rotation. The rotor of each set has a plurality of permanent magnets disposed circumferentially along an annular air gap opposite the stator poles. The permanent magnets of adjacent rotor element sets and/or the poles of adjacent stator sets are offset from each other in the axial direction to cancel the effects of cogging torque produce by each of the sets.

Abstract: The linear synchronous motor consists of a specific primary and secondary part. The secondary portion is a ferromagnetic back plate. An array of permanent magnets are attached to the back plate so that a fixed or variable pole pitch occurs in a precise manner between at least two magnets of alternating polarity which improves existing methods for attaching, guiding, protecting and enhancing the overall flux array produced and emitted by the permanent magnets. A one-piece electrically synchronous linear secondary stator member accompanies a primary member, the synchronous linear permanent magnet motor. The stator electrical frequency is customizeable to allow for a wide variety of braking applications.
