Abstract

A radial-radial magnetic field modulation type brush-less composite structure motor belongs to the field of motor, for solving the problems that in the existing serial type, parallel type and serial-parallel type driving device, the engine and other system components fail in simple and efficient cooperation, to make the system have heavy volume, complex structure, high cost, limited performance, and failure in power output. The motor comprises a radial dual-rotor motor and a radial torque modulation motor which are arranged in parallel in a case, wherein the permanent magnet rotor of the radial dual-rotor motor is driven by a prime mover to form a magnetic field of 2n polarity and the stator thereof forms a magnetic field of 2p polarity; an output shaft of a modulation ring rotor providedwith q magnetic guiding blocks and insulating blocks outputs a required rotary speed, p=abs(hn+kq), and the output rotary speed has no dependence on the input rotary speed in order to realize stepless speed variation; and the radial torque modulation motor inputs driving torque or brake torque according to the actual load requirement of the motor, to satisfy the actual torque requirement of load,thereby balancing input and output energy of the output shaft of the modulation ring rotor.

Description

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