  • Patent number: 9362786
    Abstract: A multi-phase reluctance electric motor with transverse magnetic flux which includes a stator and a rotor. The stator comprises a housing (1) and a number m of phase armature units, each being staggered at an electrical angle of 360°/m along the circumferential direction sequentially in the housing (1) along the axial direction and comprises an armature iron core, an armature coil (2) and permanent magnets (3). The armature coil (2) is embedded within an annular space formed among first, second and third annular iron core segments (6, 7, 8) of the armature iron core. The pole distance ?m between two adjacent permanent magnets (3) on the same segment and the tooth distance ?p between the rotor teeth (5) along the circumferential direction fulfil 2 ?m=?p. This motor eliminates mutual inductance between phases, improving control precision of current and electromagnetic torque and dynamic characteristics of the system.

  • Publication number: 20140125157
    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).
