DOL Motor Starting Current

Stephen Yewdall

I have done some asking and have been told that typically the starting current for a DOL motor will rise to 20 times FLC for at least a half cycle (0.01 secs in UK), then drops to around 8 times for a few seconds until the motor reaches 85% of its designed speed (revs) when it will drop to around it's FLC.

Is this a good estimate for the starting current of a DOL motor (without going over the top)? Or has anyone any experience of better estimates?

    Sounds like a fair estimate as you will be switching supply current directly across very low resistance static coiled copper conductors
