With the rapid development of integrated circuit, many industries have changed dramatically, such as the automobile industry. Motor controller is a kind of integrated circuit applied in automobile, which plays a very important role.
What is a motor controller?
For the definition of motor controller, the official explanation is that it is an integrated circuit that controls the motor to work according to the set direction, speed, angle and response time through active work. In the electric vehicle, the function of the motor controller is to convert the electric energy stored in the power battery into the electric energy needed to drive the motor according to the commands of gear, accelerator, brake, etc., so as to control the starting operation, climbing force and other driving states of the electric vehicle.
Based on different research purposes, there are many kinds of motors. At present, the motor of electric vehicle basically uses AC motor. At present, the main motor of main vehicle is permanent magnet AC motor, which has three characteristics: one is simple structure and reliable operation; the other is small size, light weight, low power consumption and high working efficiency; the third is flexible shape and size of motor. The motor controller is composed of inverter and controller. Among them, the inverter receives the DC power from the battery and reversely turns into three-phase alternating current to provide power for the automobile motor. Secondly, the controller receives the motor speed and other signals and feeds them back to the instrument. When braking or acceleration occurs, the controller controls the frequency rise and fall of the inverter, so as to achieve the purpose of acceleration or deceleration.
