Abstract

The invention discloses an axial-axial radial magnetic field modulation type brushless composite structural motor, which belongs to the motor field and solves the problems of heavy system volume, complex structure, limited performance and incapability of effectively outputting power because engines and other system components in the conventional series, parallel and series-parallel 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 an axial radial torque adjusting motor respectively, the permanent-magnetic rotor of the axial double-rotor motor is driven by a prime mover to form a 2n-pole magnetic field, the stator of the axial double-rotor motor forms a 2p-pole magnetic field, the output shaftof a modulation ring rotor consisting of q magnetic conducting blocks and insulating blocks outputs the required rotational speed, the p is equal to the absolute value of hn and kq, and the output rotational speed does not depend on the input rotational speed so as to realize stepless speed change; and the axial radial torque adjusting motor inputs a driving torque or a braking torque according to the actual load requirement to meet the actual torque requirement of a load so that the energy input and output by the output shaft of the modulation ring rotor is balanced.

Description

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