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 increased by 4.5-5 times compared with when 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.

The non-inductive integrated motor-generator also includes an annular magnetic field formed in the casing, a plurality of coils arranged in pairs, and a control unit. The annular magnetic field is formed in the housing with the main shaft as the center, the magnetic field direction of the annular magnetic field is located on the radial direction of the main shaft, and the annular magnetic field is configured as two parts of the annular main shaft with equal distribution and opposite magnetic field directions. Each turn in the coil partially passes th...

Description

technical field [0001] The present invention relates to the technical field of electric motors, in particular to a non-inductive motor-generator integrated machine. The invention also relates to an electric vehicle. Background technique [0002] At present, both the motor and the generator adopt the cogging structure, the coil is embedded in the iron core cogging, and the coil in the iron core cogging is energized to generate an alternating magnetic field to generate the rotating driving force of the motor, or, due to the rotation of the generator The resulting magnetic field cuts to generate an electromotive force in the coil. The alternating magnetic field produces magnetic domain losses and eddy current losses. Moreover, in the DC permanent magnet motor, due to the uneven distribution of the cogging, there is also the torque loss of the cogging, which greatly reduces the efficiency of the motor or generator. [0003] In addition, the increase or decrease of the magneti...
