The compressor oil is new and thanks so much for the reply I am going to chase the rotational force today and measure the rpm, I will let you know the results later. Thanks again!!!

Voltage is 245 when not running, upon startup voltage drops to 180 and during normal running voltage is 230.

Hi everyone, I recently purchased a world aire 10hp 120 gallon 2 stage compressor, when I looked at the compressor it would only buzz when turned on so having fixed a few of these issue I knew it was a capacitor issue. I got the compressor home changed out all 4 capacitors and was in business (or so I thought). Upon startup the compressor is drawing far too many amps. The compressor has a Baldor motor that is rated at 39 running amps, during normal running it’s is drawing between 45 and 50 amps during start up it is drawing between 320 and 370 amps depending on cut in pressure. My shop currently has a15 kva transformer on the pole with a 1/0 drop 75 feet to the building, from the breaker panel I have 60 ft of 6 awg wire and a 60 amp breaker. I have checked the unloader valve and it works perfect. I have spoken to a couple motor shops and they think it’s a voltage issue and when I speak to the power company they think it’s a motor issue. Do any of you know if anything internally in that motor can cause it to draw way too many amps on start up PLEASE HELP!!!
