An U-shaped
stator hybrid-excitation switch reluctance
machine belongs to the field of an electrical
machine. The U-shaped
stator hybrid-excitation switch reluctance
machine comprises a rotor and a plurality of U-shaped
stator blocks arranged at the circumference of the rotor, the outer side of rotor teeth of the rotor is shaped as outer arc, the inner side of stator teeth of the U-shaped stator blocks is shaped as inner arc, a gap is arranged between the outer arc of the rotor teeth and the inner arc of the stator teeth, the plurality of U-shaped stator blocks form a modular stator, excitation windings are wound around the two stator teeth of each U-shaped stator block, a permanent
magnet is arranged at the inner side of each U-shaped stator block, and the magnetizing direction of the permanent
magnet is magnetized tangentially. When the
phase number of the electrical machine is m phases, the number rate of the stator teeth to the rotor teeth of the electrical machine is 2m to (2m-1), for example, when the
phase number of the electrical machine is three phases, the electrical machine is structurized with
three phase 6 / 5 and
three phase 12 / 10. In the U-shaped stator
hybrid-excitation switch reluctance machine, the stator is the modular stator, modular production is promoted,
interphase magnetic paths are not coupled and completely separated, and meanwhile, the electrical machine has the advantages of high output, simplicity in structure, high fault-tolerance capability and high reliability, is easy to maintain, and is convenient to control.
