摘要： A stepping motor of the homopolar design with a step angle of 3.6.degree. and having a generally cubic form is disclosed. The motor includes a generally square, single-section laminated stator which has only four stator poles extending radially inwardly from the middle regions of the straight sides, and a concentric rotor secured to a shaft journaled in a pair of bearing bells fixed to the stator at the opposite faces thereof and having the same generally square configuration. The rotor includes a disc-shaped permanent magnet of high remanent energy density (B.times.H).sub.max .gtoreq.10.times.10.sup.6 GOe, and a pair of annular steel rotor elements provided at the working air gap with identical numbers Z.sub.r of rotor teeth of pitch .tau..sub.r =360.degree./Z.sub.r. Each stator pole is provided at the working air gap with four or five stator pole teeth of pitch .tau..sub.s =360.degree./Z.sub.s, where Z.sub.s is the theoretically maximum available number of stator pole teeth and must be evenly divisible by 4, and Z.sub.s =Z.sub.r -1.+-.k where k is an even integer and 0.ltoreq.k.ltoreq.6. A special twin-section insulation member adapted to be axially fitted into the stator from the opposite faces thereof and designed to permit simultaneous machine winding of the field windings onto the respective stator poles is also disclosed. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

摘要： A self-starting synchronous or stepping motor has at least two phases, a permanent magnet rotor and a stator including individually excited and inwardly facing main stator poles. The stator poles and rotor poles have a predetermined spacing of .tau.p. The stator poles are combined in groups of alternate polarity. The groups are displaced by a predetermined angle. At least one windingless auxiliary stator pole of approximately one-half of the width of the main stator pole is provided per group in addition to the main stator poles. The total number of stator poles is at least equal to the number of rotor poles. Additional auxiliary poles may be either half-pole widths or pointed shape. Embodiments of two-phase and three-phase synchronous motors are disclosed.

摘要： In the disclosed motor arrangement, a single stator operates with one of eight rotors having a number of teeth equal to Z.sub.R = 5u(n + 1) .+-. gu. In the equation, n is one less than the number of teeth on each pole of the stator, u is equal to the number of pole groups, and g is any integer varying from 1 to 4. Energizing the poles of the motor is one of five winding arrangements. The motor, with a single stator, is capable of stepping at one of 40 stepping angles.
