I have been trying to get my RPC running using the plans from http://home.att.net/~waterfront-wood...econverter.htm
I followed the recommended capacitor values for my 5 hp motor however, when the power is applied to the motor it makes a bad chattering noise and the motor only runs at about half or less of its rated RPM (1750). I have tried changing the capacitor values and also turning the motor shaft initially with a cord all without any luck.
The motor is a 4 pole induction motor - 3 phase (obviously) that is wired for 220 but can be wired 440. I do not know the history of the motor but when i performed a continuity check btwn each of the winding wires and the outside motor case and it seems that a couple of windings (3 to be exact - one on both the L1 and L2 lines and one on the 3 wires that are tied together to specify 220 volt input), do not have continuity with the motor case.
Does this mean that the motor is fried? Am i doing something wrong?
If the motor is fried, does anyone have a 7.5 hp or 10 hp 3-phase idler that they would want to get rid of cheap? (preferably close to vancouver BC, Canada)
Thanks a lot for any help
