新型数控机床主轴交流电机变频调速数控系统

The New Mode Frequency-Changer Governor NC System for Mainshaft Alternating Current Dynamo of Machine-Tool

介绍了一种主轴交流电机变频调速数控系统。由于采用正弦波脉宽调制技术 ,能很大程度的减少因变频器输出交流电正弦波失真所造成的转矩脉动和电机损耗。

This paper deals with a variable\|frequency speed control system for mainshaft AC motor, and which, adopting sine wave pulse with modulation can greatly reduce the torsional pulsation,and AC motor loss oweing to sine wave distortion at alternating\|current output in varible\|frequency inverter.
