基于FPGA的无刷直流电机调速系统设计与实现

The design and achievement of adjustable speed system in no brush DC motor based on FPGA

以FPGA为控制器,使用霍尔传感器进行电机电流及位置的检测,用MOSFET搭接成的驱动电路进行控制电机的转速和转向,用VHDL语言设计了一种PWM调节电机速度的方法。通过对系统进行理论分析以及调试,实现了电机电流、位置的检测并控制电机速度和转向从而达到要求的速度和方向。

In this paper, FPGA is used as controller, using Hall sensor to detect current and the location of the motor , using drive circuit made by MOSFET to control speed and steering, of the motor, and a method is designed using PWM adjusting motor speed with VHDL language . Through theoretical analysis and debugging, this design can achieve the detection of current and position of the motor, can also control the motor speed and the steering to achieve what we want.
