Abstract

The invention relates to a radial-axial magnetic field modulation type brushless composite structure motor, belonging to the motor field. The invention solves the problems that system volume is large, structure is complex, cost is higher, performance is restricted and power can not be effectively output as the engine and other parts in the existing serial type, parallel type and hybrid type driving device can not simply and efficiently coordinate. In the motor of the invention, a radial double rotor motor and an axial torque regulating motor are arranged in parallel in the case, the p-m rotorof the radial double rotor motor is driven by a prime motor, so as to form 2n polar magnetic field, and the stator thereof forms 2p polar magnetic field, the required rotating speed is output by the output shaft of a modulation ring rotor provided with q concentrating flux blocks and insulation blocks, and p is equal to the absolute value of hn+kq, the output rotating speed thereof is independentto the input rotating speed, thus stepless speed change is realized; and the axial torque regulating motor input a driving torque or a braking torque according to the actual load requirement, so as to meet the actual torque requirement of load, so that the energy input by the output shaft of the modulation ring rotor is balanced with the energy output by the output shaft of the modulation ring rotor.

Description

technical field [0001] The invention relates to a radial-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...
