Abstract: The present invention relates to a multiphase segmented high-power synchronous machine with transversal flux guidance consisting of at least two or more double segments. The two or more double segments form segments of a linear motor or generator or segments of a rotating motor or generator. The two or more double segments consist of a row of permanent magnets and soft-magnetic yokes with one or more circumferential windings. As a result of a bidirectional structure in each case winding currents of the same magnitude flow through two equally large segments. As a result of a phase-shifted arrangement of the yokes, the thrust torque is effected in the same direction of motion. The yokes can be arranged folded down or lying side by side.

Abstract: Disclosed is a poly-phase reluctance electric motor with transverse magnetic flux, which electric motor is composed of a stator and a rotor. The stator is composed of a housing (1) and a number m of phase armature units which are arranged within the housing (1) along the axial direction successively, with each of the phase armature units being staggered at an electrical angle of 360°/m along the circumferential direction. Each phase armature unit is composed of a unit armature iron core, an armature coil (2) and permanent magnets (3), with the unit armature iron core being composed of a first annular iron core segment (6), a second annular iron core segment (7) and a third annular iron core segment (8). The armature coil (2) is embedded within an annular space formed among the first to the third annular iron core segments (6, 7, 8). The permanent magnets (3) are fixedly arranged on the inner surfaces of the first and the third annular iron core segments (6, 8) along the circumferential direction in a manner of the N pole and the S pole spaced successively. The pole distance τm between every two adjacent permanent magnets (3) on the same annular iron core segment and the tooth distance τp between the rotor teeth (5) arranged along the circumferential direction fulfil 2τm=τp. The electric motor eliminates the mutual inductance between phases, improving the precision with which the current and electromagnetic torque of the electric motor can be controlled and the dynamic characteristics of the system, and improving the reliability and safety of the motor as a result of the permanent magnets (3) being located on the stator.

Abstract: Provided are multiple switched reluctance motors and excitation control methods for same. Motors with various structures are provided having the same structural characteristics, a stator formed of an even number of salient pole pairs and a rotor formed of an even number of salient pole pairs. The salient poles of the stator salient pole pairs are arranged opposite the salient poles of the rotor salient pole pairs, with minimal air gaps left between said salient pole pairs, thus leaving the shortest magnetic return paths between the stator salient pole pairs and the rotor salient pole pairs arranged opposite one another, thus satisfying the minimum reluctance principle of the switched reluctance motor. In addition, due to the magnetic isolation between each stator salient pole pair, the performance of the magnetic pole of each stator salient pole pair is controlled by an excitation control power source and changed independently.
