Motor Control System

In order to improve the controllability and safety of electric vehicle, the flexibility of the motor control system, and ensure the service life of the motor controller, a kind of brushless DC motor control system that used microcontroller with special integrated circuits is suggested in this paper. Introduced the control scheme and operational principle of the control system, given the main hardware circuit, and expounded the control strategy and software design of system. In this control system, the microcontroller is mainly used to control special integrated circuits, implement good man-machine conversation and control strategy, as well as the management of the lead-acid battery; Special integrated circuits main to control the motor, alleviate the pressure of microcontroller effectively, guarantee the microcontroller to complete other work better. The test result indicates that the control system have a simple structure, response quickly, good reliability.

Motor Control System

Brushless DC Motor is a kind of a new motor which commutation signals replaces traditional motor mechanical structure with electronic signals. Square wave brushless DC motor can be divided into sensor motor and sensorless motor. Position sensor will increase system cost, motor size and maintenance difficulty, which bring about limitation and limits to promote its application in all areas. This project designs sensorless BLDC Motor control system with the core of the stm32 micro-controller and uses Back-EMF zero-crossing detection method. In the system designing software control algorithm, drawing schematic diagram of hardware and making PCB board have been completed dependently. The experimental results show that the system can well realize the starting and running of sensorless BLDC Motor control system, and have a good measure of protection.
