Abstract

The invention provides a novel permanent magnet electronic gearbox for an automobile. The novel permanent magnet electronic gearbox mainly comprises an engine, a motor shaft, a conductor rotor, a steel body, a copper conductor, a magnetic rotor, a permanent magnet and the like. The conventional physical transmission between a motor and a load is replaced by an air gap torque transmission mode. Theengine is controlled by an electronic control system, and the engine is connected with the magnetic rotor. A motor is not mechanically connected with a load shaft, and a load protection function is achieved. The most difficult problem that a motor is burnt due to overload or locked-rotor frequently occurring in the running process of the motor in a driving system is easily solved, and vibration and noise can be reduced. The device is of a pure mechanical structure, does not consume electricity, does not generate harmonic waves, electromagnetic interference or other pollution, and is a green and environment-friendly product. Buffer starting and multiple times of starting can be achieved.

Description

technical field [0001] The invention relates to a gearbox, in particular to a novel permanent magnet electronic gearbox for automobiles. Background technique [0002] The gearbox of the prior art relies on the principle of levers and gears to realize the physical connection mode of automobile drive. This method has the disadvantages of high energy consumption of the motor and obvious system vibration. [0003] It is still a new topic to apply permanent magnet drive technology to the automotive field. Permanent magnet magnetic drive technology is a new technology that uses the magnetic force of permanent magnet materials to realize the contactless transmission of force and torque (power) based on the basic theory of modern magnetism. The devices that implement this technology are called permanent magnet drives. [0004] In 1940, the British used magnetic drive pumps for the first time to solve the leakage problem of chemical pumps with dangerous media. In 1999, the MagnaD...
