光电式直流电机的分析研究

Analysis of the Photoelectric DC motor

光电式直流电机的运行速度控制精度高、误差较小。其产生的电磁干扰无法传递到控制系统中,使电机运行更加稳定,因此研究光电式直流电机的意义非常重大。本文介绍了光电耦合器的原理及作用、直流电机的工作原理以及测量光电式直流电机速度的方法及并分析总结影响电机速度的主要因素。

Photoelectric DC motor speed control is of high precision, little error. The generated electromagnetic interference can not be transmitted to the control system, the motor can run more stable, so the study of photoelectric DC motor is very important. This paper introduces the principle and function of photoelectric coupler, DC motor and the principle of measuring photoelectric DC motor speed method and summarized analysis of the main factors influencing the speed of the motor.
