I recently aquired a couple of 3 phase Yale Chain Hoists. They are wired for 440. I only have 220. When I opened them to switch wiring....there were no extras. 3 wires come directly from the windings. I have a diagram from the company but haven't a clue what to do next.

Rewire 3 Phase Mtr 440 t0 220(electrical)
- Thread starter tbs
- Start date
TBS------IF THE MOTORS ARE RATED AT 440V WITH ONLY 3 LEADS FOR SUPPLY THEN IT MAY BE RUN ON 220V SUPPLY,BUT THE INTERNAL CONNECTIONS WILL HAVE TO BE CHANGED ie THE MOTORS YOU HAVE ORIGINALY MAY HAVE "STAR"CONNECTIONS IN THE WINDINGS. SO TO RUN ON 220V 3PHASE THE MOTORS WILL HAVE TO BE RE-CONNECTED TO "DELTA" CONNECTIONS. I HOPE THIS ADVICE WILL HELP YOU. GOOD-LUCK.

I have a small AC electric motor which I am trying to use for another application. The motor has four connections with white, green, black and red wires attached. Someone else in the history of this motor combined the white/green and the red/black in order to use a two prong plug. The power cord is shot and I am trying to replace it, but am unsure of how to connect the four wires into three. Any suggestions?
