Problems solved by technology
[0004] However, with the increase of motor power, compared with permanent magnet motors, switched reluctance motors still have problems such as low system efficiency and effective utilization of materials, large vibration and noise, and low power factor. It has affected its use and promotion in the field of direct drive wind power generation
[0005] It can be seen that there are still obvious deficiencies and defects in the structure and use of traditional switched reluctance generators, which need to be further improved. The weight and cost of the fixed shaft support double air gap direct drive switched reluctance wind turbine and its unit system to reduce vibration and noise are really one of the important topics of current research and development

The invention relates to a fixed-shaft-supporting double-air-gap direct-drive switch magnetic resistance wind driven generator and a unit system thereof. The wind driven generator comprises a motor shell, a wheel hub, a fixed shaft, a hollow rotating shaft, a rotor turntable, a rotor, an outer stator, an inner stator and an inner stator centering bearing, wherein the rotor is fixedly connected with the hollow rotating shaft through the rotor turntable, and the hollow rotating shaft is linked with the wheel hub; and an inner ring of the inner stator centering bearing is connected with the rotor turntable, and an outer ring is connected with the inner stator. The system comprises the switch magnetic resistance wind driven generator, a power converter, a control system, an inverter and a load. Compared with a single-stator switch magnetic resistance generator, the output power of unit size of the motor can be increased, so that the size and the weight of the motor can be reduced, the cost is reduced, and convenience in transportation can be realized.
