Abstract

The invention provides a high-power density reluctance motor. The high-power density reluctance motor comprises a rotor, a rotor shell and a winding, wherein the rotor is arranged in the rotor shell,the winding comprises a plurality of coils, the coils all are wound around the rotor shell, the rotor comprises a circular-annular rotor body and a gear group, the rotor shell is of a circular-annularstructure of a non-magnetic conduction material, the circular-annular rotor body is formed by alternatively arranging and connecting N tile-shaped silicon steel arc blocks and N non-magnetic conduction filling arc blocks, the gear group comprises an inner gear ring and a gear shaft, the inner gear ring is fixed on an end surface of the circular-annular rotor body, the inner gear ring and the circular-annular rotor body are concentrically arranged, a gear end of the gear shaft is engaged with the inner gear ring, a shaft end extends out of the rotor shell, and the tile-shaped silicon steel arcblock and the gear ring are fixedly connected to form a single-phase iron core. By the high-power density reluctance motor, the problem of low power density of an existing switched reluctance motor is solved; and meanwhile, by the structure, the system noise is also reduced.

Description

【Technical field】

[0001] The invention relates to a reluctance motor. 【Background technique】

[0002] Theoretical research and practice of switched reluctance motors have proved that the system has many significant advantages: the motor structure is simple and strong, the manufacturing process is simple, the cost is low, and it can work at extremely high speeds; the stator coils are easy to embed, and the ends are short and It is solid and reliable, and can be used in various harsh, high temperature and even strong vibration environments. The loss is mainly generated in the stator, and the motor is easy to cool; the rotor has no permanent magnets, which allows a higher temperature rise. The direction of torque is independent of the direction of current, which simplifies the power converter to the greatest extent and reduces system cost. The power converter will not have a shoot-through fault and has high reliability. Large starting torque, good low-speed performance, and ...
