摘要
为了降低无刷直流电机控制器的内部电路的复杂性,提出了一种结构简单的专用电路,可用于驱动无刷直流电机的微控制器。通过电动机上位置传感器将转子位置信号传递给控制器电路,并得到位置传感器的输出真值表,然后利用Logisim软件,得到对应的数字逻辑电路。利用Cadence的仿真工具NC-Verilog simulator得到仿真波形。以80C51为主控芯片,通过外接电路的方式完成最终的验证分析。通过此专用电路将可使电动机的转子顺时针或逆时针方向旋转。此专用电路可用于生产成本低廉和对控制精度要求不高的无刷直流电机控制器。
In order to reduce the complexity of the internal circuit of brushless direct current motor(BLDCM) controller, a special circuit with simple structure is proposed, which can be used to drive the microcontroller of BLDCM. The position signal of the rotor is transmitted to the controller circuit by the position sensor on the motor, and the output truth table of the position sensor is obtained. Then the corresponding digital logic circuit is obtained by using Logisim software. The simulation waveform is obtained by using the simulation tool NC-Verilog simulator of Cadence. With 80C51 as the main control chip, the final verification and analysis is completed by the way of external circuit. Through this special circuit, the rotor of the motor can rotate clockwise or counterclockwise. This special circuit can be used for the controller of brushless DC motor with low cost and low control precision.
