    摘要: A rotating electromagnetic apparatus has a stator frame supporting spaced apart pairs of permanent magnets which are arranged with like magnetic poles mutually facing. A toroidally shaped rotor frame is radially wound with a plurality of wire coils immersed within slots in the in rotor frame, the slots positioned adjacent to the opposing magnets. An electromechanical commutator is used to direct current between an outside source or sink through brushes to rotating multiple contacts simultaneously. The brushes are triangular in cross section. The coils may be connected in series or parallel interconnection.

    摘要: Brushless repulsion motors are presented, in which rotor coils switching signal detectors are selectively located in spaced angular relationship on the rotor and signaling sources are distributed around all or most of the stator circumference to allow looser tolerances for motor manufacturing and improved controllability of rotor coil actuation during operation. Asymmetric stator poles are also provided for brushless repulsion motors to mitigate torque ripple and vibration, in which the shape of the stator pole tips is tailored by varying the angular length of the pole section.

    摘要: A commutator motor having excellent performance of preventing coils from being burnt at overload can operate from either AC or DC power sources. This commutator comprises an iron core having plural slots, a rotation shaft inserted in a center of the iron core, and a pair of first and second commutators mounted on the rotation shaft at opposite ends of the iron core. A first coil wire is connected to the first commutator, and is wound on bottoms of the slots to form an inner coil. A second coil wire having a smaller diameter than the first coil wire is connected to the second commutator, and is wound on the inner coil in the slots to form an outer coil.
