Non-inductive electric power generation all-in-one machine and electric vehicle

Abstract

The invention provides a non-inductive electric power generation all-in-one machine and an electric vehicle. The non-inductive electric power generation all-in-one machine comprises a shell, a main shaft, an annular magnetic field formed in the shell, a plurality of groups of coils arranged in pairs and a control unit. The magnetic field direction of the annular magnetic field is located in the radial direction of the main shaft, and the annular magnetic field is configured into two parts which are equally distributed around the main shaft and opposite in magnetic field direction. Each turn of circuit in the coils partially passes through the annular magnetic field, and the two coils in the same group are arranged in parallel, are wound reversely, are distributed in a central symmetry manner by taking the main shaft as the center, and respectively pass through two parts of the annular magnetic field. And the control unit controls the current commutation of one group of coils or the on-off of a plurality of groups of coil circuits. And the annular magnetic field and the coil are fixedly arranged on one of the shell and the main shaft respectively. The non-inductive electric power generation all-in-one machine is arranged based on the Lenz's law, and can weaken the adverse effect of the alternating magnetic field and magnetization curve characteristics of the motor coil on the energy conversion efficiency of the motor.

Description

Technical field [0001] The present invention relates to the field of motor technology, and more particularly to an ineffective electric generator. The invention also relates to an electric vehicle. Background technique [0002] At present, whether it is an electric motor or a generator, the coil is embedded in the iron core teeth, and the iron core dental circle generates an alternating magnetic field to generate the rotational driving force of the motor, or the rotation of the generator. The resulting magnetic field cuts and generates an electric force in the coil. The alternating magnetic field generates magnetic domain loss and eddy current loss. Moreover, in the DC permanent magnet motor, since the equalization of the tooth distribution is deviated, there is also a torque loss of the tooth groove, which greatly reduces the efficiency of the motor or generator. [0003] In addition, the magnetic field strength increase or decrease in the electromagnetized core and the current ...

Problems solved by technology

This problem of the motor causes a lot of electric energy to be wasted in vain; this disadvantage is even greater in electric vehicles, the speed of electric vehicles is constantly changing, and the rated speed and torque of electric vehicle motors are designed for driving on flat roads. When the electric vehicle is running at low speed or at high speed on the highway, its efficiency will be greatly reduced, resulting in a decrease in the efficiency of converting electrical energy into kinetic energy;

[0004] The above-mentioned problems of existing motors, due to the magnetization curve characteristics of ferromagnetic materials and the existence of magnetic domain loss, in electric vehicles, even if the current input to the coil in the motor is 4.5-5 times higher than that of driving on a flat road, its output However, the torque cannot be increased proportionally, and the conversion efficiency between electric energy and kinetic energy is limited, which also has an adverse effect on the battery life of the electric storage unit.
