Abstract

The invention provides a double-stator electro-magnetic double-salient starter generator capable of effectively utilizing internal and external space of a rotor. A unit motor of the generator is of a 12/8/6 pole structure, namely external stator pole number of the motor is 12N, rotor pole number is 8N, internal stator pole number is 6N, and N is a natural number. The external stator and the rotor of the motor is matched with a traditional 6/4 pole unit motor in pole number. External stator pole arc coefficient is 0.5. The internal stator and the rotor of the motor is matched with a 6/8 pole unit motor in pole number, and the internal stator pole arc coefficient is 0.25. Phase difference of an internal armature winding and an external armature winding of the motor is 60-degree electrical angle and is capable of achieving small phase-shifting torque pulsation. The starter generator completely utilizes internal space of the starter generator of a flat structure and is suitable for being applied to automobiles and small combustion engines.

Description

technical field [0001] The invention relates to an electric excitation double salient pole starter generator with inner and outer double stators, which belongs to the technical field of automobile starter generators. Background technique [0002] Electric excitation double salient pole motor is a new type of motor composed of position sensor, power electronic power converter, excitation power circuit, controller and motor body with salient pole stator and rotor structure. The unit motor of the traditional electric excitation double salient pole motor adopts the 6N / 4N pole structure of the inner rotor, the number of stator poles is 6N, the number of rotor poles is 4N, and N is a natural number, indicating the number of unit motors. Due to the small number of rotor poles and high speed, the motor usually adopts a larger slenderness ratio to increase the power of the motor. This kind of motor is very suitable as an aviation starter generator. For applications using small inter...
