I've never run into a 3 phase motor that wouldn't change directions just by swapping one of the two leads.
it's not a 3 phase motor I don't believe. That's why it has a capacitor.I've never run into a 3 phase motor that wouldn't change directions just by swapping one of the two leads.
Be carful! It could it be that the grinder was dissembled at some point and put back together backwards. That is to say, the guards & base facing the wrong way. I recently restored a bench grinder and realized that was a possible error. You can determine if the motor rotation is correct by checking which way the shaft nuts are threaded, if the nuts will tighten by holding them and turning the shaft in the direction it is now rotating, the rotation is correct. If you reverse the motor the nuts would want to loosen, possibly creating a dangerous condition.
