Abstract

The invention relates to an axial-axial magnetic field modulation type brushless composite structure motor, belonging to the field of motors. The invention aims at solving the problems of large system size, complex structure, high cost, limited performance and ineffective power output because an engine and other components of the system can cooperate simply and efficiently in the traditional serial, parallel and mixed drive devices. In the invention, a case is divided into two parts which are respectively provided an axial dual-rotor motor and an axial torque regulating motor, wherein a permanent magnet rotor of the axial dual-rotor motor is driven by a prime motor to form a 2n magnetic field, a stator forms a 2p magnetic filed, an output shaft of a modulation loop rotor with q magnetic blocks and insulated blocks outputs a required rotating speed, p is equal to the absolute value of hn+kq, the output rotating speed does not depend on the input rotating speed, and stepless speed change is realized; the axial torque regulating motor inputs drive torque or braking torque according to actual load need, the actual torque need of the load is satisfied, and thus, energy input and outputby the output shaft of the modulation loop rotor are balanced.

Description

technical field [0001] The invention relates to an axial-axial magnetic field modulation type brushless composite structure motor, which belongs to the field of motors. Background technique [0002] Fuel consumption and exhaust emission pollution of traditional internal combustion engine vehicles are hot issues of worldwide concern. The use of electric vehicles can achieve low energy consumption and low emissions. However, due to the energy density, lifespan, and price of batteries, which are one of the key components of electric vehicles, the cost performance of electric vehicles cannot compete with traditional internal combustion engine vehicles. Under such circumstances, hybrid electric vehicles, which combine the advantages of internal combustion engine vehicles and electric vehicles, develop rapidly and become a hot spot in the development of new vehicles. [0003] The characteristics of the existing serial driving device are: the engine can be operated stably in its b...
