PG电机在EFT测试时的抗干扰控制

Anti-jamming Control Technique of PG-motor in EFT Test

一般PG电机基本采用PWM过零调节技术来实现速度控制,在EFT干扰下,通过改善过零控制和反馈控制来抑止EFT干扰引起的电机转速波动和电机本体振动。

PG-motor is used to set PWM by zero-crossing detection to realize controlling of the speed. In EFT test,By improving zero-crossing detection and speed feedback detection,PG-motor can run stable with no dithering .
