| This solution uses hydraulic method to perform mechanical weak magnetic field adjustment, and its mechanical principle is similar to the CVVT valve adjustment technology of mechanical engines. CVVT technology uses hydraulic transmission to adjust the engine intake volume according to the engine speed and then adjust the engine’s working efficiency. The magnetic solution uses hydraulic transmission to adjust the mechanical weak magnetic field of the motor, and then cooperates with the motor to achieve the appropriate back electromotive force according to the speed to improve the working efficiency of the motor. |
