    Induction Motor Power Factor and Mechanical Load

    Thanks for the help. From a generic design point of view, how is this relationship explained? I can see that current does not vary significantly with load, hence high VA in with low Watts out = low power factor. I just don't understand why this is the case. LionelHutz mentions the electrical...

    Motor turn down - what does it mean?

    Sure someone else can explain this a bit better than I can but as far as I'm aware, turndown ratio is simply the ratio of the rated speed to the minimum speed at which the motor can handle the rated load. Therefore a higher turndown ratio implies slower speeds are possible without causing...

    Induction Motor Power Factor and Mechanical Load

    Can someone please explain to me (quantitively prefered) how to determine the power factor of a 3-phase induction motor at a load less than the rated load? I've been able to find methods of improving power factor through voltage control etc, but haven't been able to prove the actual relationship.
