Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] The invention is a double-rotor permanent magnet motor applied to wind power generation, which is suitable for a wide wind speed range, and its structure includes a motor stator and an inner and outer rotor of the motor. The motor stator includes stator core 1 and stator winding 2; the inner rotor of the motor includes inner rotor iron core 5 and inner rotor permanent magnet 4, and the outer rotor of the motor includes outer rotor iron core 7 and outer rotor permanent magnet 8; There is an inner air gap 3 between them, and an outer air gap 6 between the outer rotor and the stator. The inner and outer air gaps of the motor are respectively formed between the inner and outer rotors and the stator, and the formation of double air gaps increases the effective air gap area of the motor.
[0025] The stator core and rotor core are composed of silicon stee...
