摘要
本文提出了一种直流电机齿谐波电势的检测方法.该方法是在直流电机极掌表面上安置一个线圈,从而检测出齿谐波电势,为直流电机工作在恶劣振动环境下提供了一个新的转速测量传感元件.试验和应用结果表明,该方法简便易行,测速准确.
This paper presents a checkout method of slot harmonic potential on DC electric mechines. A coil is installed on pole shoe to check slot harmonic potential. It provides a new kind of sensor element for measuring speed of DC electric machines working in environment with evil vibration.The results of test and application proved that the method is simple, convenient and accurate in measuring speed.
