You have a 50/60 hz 4 pole motor. At 60Hz it is only useable at 460v, probably due to the amount of backiron, but at 50Hz you can connect it Delta for 220-240v or Wye (star) at 380-420v. It is 3 phase, seen at the top, and the RPM factoring in slip, at 50Hz is 1455 rpm and at 60Hz is 1755 rpm. If you know how manyu leads, there are references on how to connect for Wye or Delta. Usually a six lead motor is W1 U1 and V1 to L1 L2 and L3 respectively, and tie together W2 U2 and V2 for Wye, Or if labeled 1-6, 1 2 3 to line 4-5-6 together. Let me know if you need more info, Part of our business is motor repair so we have extensive reference material.
