Abstract

The invention discloses an axial-radial magnetic field modulation type brushless composite structural motor, which belongs to the field of motors and solves the problems of heavy system volume, complex structure, high cost, limited performance and incapability of effectively outputting power because an engine and other system components in the conventional series, parallel and parallel-series driving devices cannot be simply and efficiently matched. A shell is divided into two parts which are provided with an axial double-rotor motor and a radial torque adjusting motor respectively, a permanent-magnetic rotor of the axial double-rotor motor is driven by a prime mover to form a 2n-pole magnetic field, a stator of the axial double-rotor motor forms a 2p-pole magnetic field, an output shaft of a modulation ring rotor consisting of q magnetic conducting blocks and insulating blocks outputs the required rotating speed, and p is equal to an absolute value of hn and kq, wherein the output rotating speed does not depend on the input rotating speed, so infinitely variable speed is realized; and the radial torque adjusting motor inputs a driving torque or a braking torque according to the actual load requirement so as to meet the actual torque requirement of the load and balance the input and output energy of the output shaft of the modulation ring rotor.

Description

technical field [0001] The invention relates to an axial-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 ...
