I have recently bought some older equipment and Motors Say three phase but there are four wires coming out of them. The first I need it running immediately so I took the motor in to A Motor specialist Because I was unable to find any information on how to wire it. The nameplate wiring schematic showed six tabs yet there were only four wires. The guy in the shop rewire the motor for three phase and said that it was a single phase motor conversion back sometime ago. I had never heard of two phase before looking in the control box of one of these machines And they mentioned two phase wiring. I don’t believe Motor I took in was single phase I believe it was two phase. Are these motors wired hot1, neutral2, hot3, neutral4??? Or do you believe they are three phase that requires a neutral ? Sorry if it seems like a stupid question but All four pieces of equipment have motors with four taps coming out I really don’t wanna spend $1000 a piece to have them all rewound can someone help me???
Thank you
