A 3 phase induction motor consists of two major parts. A three phase induction motor is a type of ac induction motors which operates on three phase supply as compared to the single phase induction motor where single phase supply is needed to operate it.

Connection of 3 phase induction motor. This video explains how to wire a three phase induction motor to an external electricity source.

A three phase motor may be set up in one of two configurations. Also these motors have either six or nine leads. The three ends of three phase windings are permanently connected to these slip rings. The first step is to figure out the voltage of your phases.
That being said there is a wide range of different motors and what you have on hand can be completely different. Capacitor motor single phase wiring diagrams always use wiring diagram supplied on motor nameplate. In tefc motors interior heat losses are dissipated indirectly through enclosure fins mostly by forced air convection. A stator a rotor. It mean terminal cooper plate w2u2 and v2 connect in one linehere i attached picture about motor terminal in star position. Make sure that the voltage you will be supplying to your motor matches the specifications on the faceplate.
Turn off the power supplying the circuit to be wired to the motor. A y type often written wye as its pronounced or a delta type. The three phase supply current produces an electromagnetic field in the stator winding which leads to generate the torque in the rotor winding of three phase induction motor having magnetic field. It also shows the difference between delta and star connections used to connect the motor coils. As its name indicates three phase slip ring induction motor consists of slip rings connected on the same shaft as that of the rotor. Step 2 open the motor wiring box and identify the wires within.
From this motor nameplatewe can see it have 2 connection and 2 voltage valueif our power supply voltage is 415 vac for 3 phasewe need to setting the motor terminal in star connection. A three phase motor must be wired to a three phase supply. A three phase motor must be wired based on the diagram on the faceplate. The three end terminals are connected together to form a star connection. In the united states for low voltage motors below 600v you can expect either 230v or 460v. Three phase totally enclosed fan cooled tefc induction motor with end cover on the left and without end cover to show cooling fan.
