Problems solved by technology

However, the problem with this structure is that the inner motor formed by the inner rotor and the outer rotor is uncontrollable when the dual mechanical port motor is working, resulting in low efficiency of the dual mechanical port motor
This structure has good heat dissipation, but this structure has a large volume and large torque fluctuations, especially it cannot meet the needs of electric stepless speed regulation systems including hybrid vehicles.

Abstract

The invention discloses a permanent magnet reluctance type double-rotor motor. The permanent magnet reluctance type double-rotor motor comprises a stator, an outer rotor, an inner rotor, an inner rotating shaft, an outer rotating shaft, a keel, a machine shell, an outer rotating shaft, an inner rotating shaft, a sliding ring, an inner motor power converter, an outer motor power converter, an energy storage device and two supports. By means of the permanent magnet reluctance type double-rotor motor, the advantage of the high power density of a permanent magnet motor and the advantage of the good radiating structure of a reluctance motor are combined, and the requirement of an electric stepless speed regulation system is met.

Description

technical field [0001] The invention belongs to the technical field of motors, and relates to a double-rotor motor, in particular to a permanent magnet reluctance type double-rotor motor. Background technique [0002] As the most important part of hybrid electric vehicles, dual-rotor motors naturally become a research hotspot. At present, there have been many researches on dual-rotor motors. Including permanent magnet type double rotor motor, reluctance type double rotor motor, asynchronous type double rotor motor. The double-rotor motor with the above structure has its advantages, but also has many disadvantages. Although the permanent magnet double-rotor motor has high power density, it is expensive; although the reluctance type double-rotor motor has a good heat dissipation structure, its torque fluctuation is large and the power density is low; the asynchronous double-rotor motor, although its price Cheap, but its efficiency is low.
