Abstract

The invention provides a double-mode electric power generator which comprises a rotor iron core (7), a stator iron core (8), coils, a shaft, a shell and the like. The double-mode electric power generator has a body structure as simple and reliable as that of a switch reluctance motor, some of the coils are armature coils, some of the coils can be used as armature coils and can also be used as excitation coils, and due to the novel coil structure, the power generator can run in a mode of being the switch reluctance motor and can run in a mode of being an electric excitation double-salient-pole motor. A controller can automatically select working modes according to different working environments, and advantages of the switch reluctance motor and an electric excitation double-salient-pole power generator can be utilized comprehensively. The double-mode electric power generator is highly suitable for serving as a starting power generator for an automobile and an automobile driving motor, works in a switch reluctance motor mode during electromotion and works in an electric excitation double-salient-pole motor mode during power generation.

Description

technical field [0001] The invention relates to a dual-mode motor generator, which belongs to the technical field of motors and electrical appliances. Background technique [0002] A motor-generator can operate both as a motor and as a generator. Motors such as starter motors and drive motors for automobiles should have these two functions to supply power to electrical equipment after starting, or to recover braking energy after driving the car. [0003] At present, there are some applications of motor generators using permanent magnet synchronous motors at home and abroad. However, permanent magnet motors do not have the ability to quickly demagnetize. When switching loads or encountering major faults, the system will generate large voltage fluctuations, which may cause damage to other components. Therefore, the permanent magnet generator needs to be connected with an additional fault protection circuit, which increases the system cost. [0004] The switched reluctance m...
