Reluctance disc type motor

Abstract

The invention provides a reluctance disc type motor comprising a shaft, first excitation coils, a first stator iron core, first armature coils, a rotor iron core, a shell, second armature coils, a second stator iron core, second excitation windings and an end cap. The first stator iron core is provided with one groove every three first stator poles. The first excitation coils are embedded in the grooves. The first excitation coils are wound on the three first stator poles, and the winding direction of the adjacent first excitation coils is opposite. The second stator iron core is provided with one groove every three second stator poles. Second excitation coils are embedded in the grooves. The second excitation coils are wound on the three second stator poles, and the winding direction of the adjacent second excitation coils is opposite. One first armature coil is wound on each first stator pole. One second armature coil is wound on each second stator pole. The armature coils of the same phase can be connected in series or connected in parallel to form one phase of winding. According to the reluctance disc type motor, the advantages of high efficiency of a switched reluctance motor can be effectively utilized, and the characteristics of small size and high reliability of an electrical excitation disc type motor can also be effectively exerted.

Description

technical field [0001] The invention relates to a reluctance disc motor, which belongs to the technical field of special motors. Background technique [0002] Permanent magnet motors, especially miniature permanent magnet DC motors, have been widely used due to their simple structure and process and light weight. However, since rare earth permanent magnets are still relatively expensive at present, the cost of rare earth permanent magnet motors is generally higher than that of electric excitation motors, which needs to be compensated by its high performance and reduced operating costs. Therefore, permanent magnet motors are only suitable for small power applications. For high-power special motors, electric excitation motors are more suitable. [0003] With the gradual expansion of the application range of motors, motor generators have more and more extensive application values. A motor generator is a motor that has both the functions of a generator and a motor. For examp...
