Abstract

The invention discloses a radial-shaft radial magnetic field modulated brushless composite structure motor, belonging to the field of a motor, and solving the problems that the system has heavy volume, complex structure, higher price, restricted performance, and can not effectively output the power as the existing engines and other system components in serial-type, parallel-type, parallel-serial drive devices can not be simply and efficiently matched. A radial double rotor and a shaft radial torque adjusting motor are arranged in the shell of the motor in parallel; the permanent magnet rotor of the radial double rotor is driven by an original engine to form 2n poloidal magnetic field, and the stator forms a 2p poloidal magnetic field; the needed rotating speed is output by the output shaft of a modulated ring rotor with q numbered magnetic conducting blocks and insulation blocks, and p is equal to the absolute value of the sum of hn and kq; the output rotating speed thereof dose not depend on the input rotating speed; and the stepless speed change is realized; the shaft radial torque adjusting motor inputs driving torque or braking torque according to the actual load requirement, thus satisfying the actual torque requirement, and leading the energy input and output by the output shaft of the modulated ring rotor to be balanced.

Description

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