1 Answer

Answer :

This is better explained through a wiring diagram. AC 3 phasemotor has three windings. Each winding has two terminals. Lets usdenote each winding as follows. Winding 1 - A1 and A2, Winding 2 -B1 and B2. Winding 3 - C1 and C2. Main incoming supply, 3 phases,are denoted by R, Y and B. Connect R to A1, Y to B1, B to C1.Connect A2,B2 and C2 to a common point (neutral). I stronglysuggest to refer to motor name plate, its wiring diagram. You needto also check the direction of rotation.
