A reluctance disc motor

Abstract

The invention proposes a reluctance type disc motor, which includes a shaft, a first excitation coil, a first stator core, a first armature coil, a rotor core, a casing, a second armature coil, a second stator core, a first Two field windings and end caps; the first stator core has a groove every three first stator poles, and the first field coil is embedded in the groove, and the first field coil is wound around the three first stator poles And the winding directions of the adjacent first excitation coils are opposite; the second stator core has a groove every three second stator poles, and the second excitation coil is embedded in the groove, and the second excitation coil is wound around three second stator poles. The stator poles are wound and the adjacent second excitation coils are wound in the opposite direction; each first stator pole is wound with a first armature coil, and each second stator pole is wound with a second armature coil The armature coils of the same phase can be connected in series or in parallel to form a phase winding. The reluctance disc motor of the present invention can effectively utilize the advantage of relatively high efficiency of the switched reluctance motor, and also effectively utilize the advantages of small size and high reliability of the electrically excited disc motor.

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...
