Composite switch reluctance motor

2008 
The invention relates to a mixed switch reluctance motor, belonging to the electric motor field. The invention overcomes the defects that the installation of a winding is difficult, the manufacturing process is comparatively difficult, the space factor is low, and the like due to the structure of the existing switch reluctance motor. In the invention, the mixed switch reluctance motor consists of a stator and a rotor, wherein, the stator is composed of a permanent magnet, an exciting winding and a stator core; an air gap is arranged between the excircle of the rotor core of the rotor and the inner circle of the stator core, the exciting winding is embedded in an tooth socket of the stator core, while the permanent magnet is embedded into the tooth part of the stator core along the axis direction. In the invention, a high-performance tangential magnetizing permanent magnet is used, and the permanent magnet is embedded into the tooth part of the stator core along the axis direction, thus forming a mixed excitation switch reluctance motor; compared with the existing mixed excitation switch reluctance motor, the motor in the invention has unchanged number of permanent magnets and increased usable area of the stator groove winding, thus improving the performance and volume ratio and the performance and weight ratio of the motor of the invention, reducing cost and simplifying manufacturing process. The motor of the invention can be used as an electric motor and an electric generator.
