基于M/T法的无刷直流电动机智能数字式测速电路

Intelligent Digital Circuit of Speed Test for Brushless DC Motor Based on M/T Method

在剖析无刷直流电动机伺服驱动系统的速度控制要求及特点基础上 ,直接利用 BLDCM转子位置传感器输出脉冲作为测速脉冲 ,提出了一种新型基于 M/T法的智能数字式测速电路 。

The paper presents a new kind of intelligent digital circuit of speed test based on M/T method by using the output pulse of BLDCM rotor position sensor as the speed test pulse,and analyses its characteristics and mechanism in detail.
