    Hello..
    Am making a project on motor control of PMSM, while am reading some articles they mention that it decrease EMI...my question concern the EMI itself, are they so harm?, and what is are the effects of them on human being?

    Re: Emi

    As far as harm to the human being, it is very debatable just like cell phone usage. but EMI is basically the noise injected into the earth wire from your circuit or from the earth to your circuit and FCC has regulations for it.

    Without an EMI filter you can easily see that any device such as a video or TV etc will have disturbance during normal operation.
