Problems solved by technology
[0002] At present, electric motors are widely used and sold in the electric vehicle industry. The motor power is between 300W and 3000W. When the electric vehicle and the motor power are 300W, a normal person (≤75 kg) cannot climb up the 15° angle when riding. Therefore, in order to solve the problem of the climbing ability of electric vehicles, the power of the electric vehicle motor has been increased from 300W to 3000W, and the power of the electric vehicle motor is getting bigger and bigger. Although the climbing ability of electric vehicles has been solved to a certain extent However, when driving on flat roads, the torque is excessive, the work efficiency is extremely low, and the mileage is greatly reduced; this problem has not only plagued electric vehicle manufacturers for a long time, but also a problem that the majority of dealers and users are very concerned about; solve This technical problem will greatly improve the performance of electric vehicles

The invention relates to the technical field of DC brushless motor high-efficiency platform expansion intelligent control equipment, specifically to a dual-motor high-efficiency intelligent FOC drivesystem, including a power supply, a power supply circuit, a speed regulating handle, a dual-stator drive motor, and a FOC control circuit for controlling a dual-stator drive device. The dual-stator drive motor comprises a housing, a group installed in the housing and including a main motor group, an auxiliary motor group and a stator shaft. The FOC control circuit includes a speed control circuitelectrically connected to the main motor group and a torque control circuit electrically connected to the auxiliary motor group. The main motor group includes a total stator, magnetic steel and a mainrotor mounted on the stator shaft. The auxiliary motor group includes a total stator, magnetic steel and an auxiliary rotor mounted on the stator shaft. According to the dual-motor high-efficiency intelligent FOC drive system, the main motor group and the auxiliary motor group do not generate interference due to cutting magnetic lines, the working efficiency of the motor is greatly improved and working cost is reduced.
