基于MC9S12X128无刷直流电机控制系统设计

Abstract

Abstract:

A brushless DC motor control system is designed in order to meet the requirements of high precision,speed performance and low cost.In this system the microcontroller MC9S12X128 is used as the control and disposal center,and the IR2130 chip is adopted to drive the MOSFET power transistor to achieve the three phase six step PWM control of the brushless DC motor.The system has the advantages of simple structure,easy speed adjustment and low power consumption.The practical application shows that the BLDC motor runs smoothly and reliably.

Key words: MCU;brushless DC motor;drive circuit;position detection;current detection

CLC Number:

TP273+.5
