3 Phase Motor Connection Windings. That being said there is a wide range of different motors and what you have on hand can be completely different. Make sure that the voltage you will be supplying to your motor matches the specifications on the faceplate.
A three phase motor must be wired based on the diagram on the faceplate. Three lead motors the stator windings of a three lead motor may be connected as either delta or wye see figure 1. In the united states for low voltage motors below 600v you can expect either 230v or 460v.
It also covers all possible parallels.
The high voltage hv terminals have upper case letters e g. Rotor is usually made as squirrel cage and it is inserted in stators hole. The life of a three phase stator winding can be shortened dramatically when the motor is exposed to unfavorable operating conditions electrical mechanical or environmental. Among these one wire is common wire and the other wire is of the running winding and the third wire is drawn in the starting winding.
