Abstract

The invention provides an integrated motor and an actuator control method thereof. The integrated motor comprises N motor units mounted in the same housing. The N motor units are coaxial. An actuator is provided with N three-phase output respectively corresponding to the N motor units. The N three-phase output is electrically connected to the N motor units to actuate the N motor units respectively. The N motor units are the same motor units in the number of N. Every motor unit comprises a rotor and a stator. The integrated motor is reasonable in design, reduces winding current and the moment of inertia of the motor (small in diameter), improves the dynamic performance of the motor, facilitates acceleration and deceleration of electric vehicles, solves the problems of safety and the like of high-voltage electric vehicles and the problems of high current of current low-voltage electric vehicles, improves the control performance of an actuating system and improves the reliability of the actuating system.

Description

technical field [0001] The invention relates to the field of motors, in particular to an integrated motor and a driver control method thereof. Background technique [0002] The system power part of an electric vehicle includes a battery, a drive and a motor. At present, most of the batteries are lithium batteries. The lithium battery consists of 3.2V cells connected in series to form the required voltage level. In China, the highest voltage of lithium batteries reaches about 600V. In the case of the same power, such a high voltage and low current, the efficiency will be higher. However, high voltage will bring many problems, such as insulation needs to be enhanced, poor safety, high cost and so on. Therefore, there is still quite a market for low-voltage electric vehicles. [0003] The battery voltage of low-voltage electric vehicles is low, and the insulation and safety are high. Due to the low voltage, the cost of the device platform is reduced. But the difficulty is...
