A y type often written wye as its pronounced or a delta type. 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.
Three Phase Induction Motors Operating Principle
Connection of 3 phase induction motor. A three phase motor must be wired to a three phase supply. It also shows the difference between delta and star connections used to connect the motor coils. 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. Three phase totally enclosed fan cooled tefc induction motor with end cover on the left and without end cover to show cooling fan. A three phase motor may be set up in one of two configurations. This video explains how to wire a three phase induction motor to an external electricity source.
Step 2 open the motor wiring box and identify the wires within. Turn off the power supplying the circuit to be wired to the motor. That being said there is a wide range of different motors and what you have on hand can be completely different. A three phase motor must be wired based on the diagram on the faceplate. In the united states for low voltage motors below 600v you can expect either 230v or 460v. A stator a rotor.
A 3 phase induction motor consists of two major parts. Make sure that the voltage you will be supplying to your motor matches the specifications on the faceplate. The first step is to figure out the voltage of your phases. It mean terminal cooper plate w2u2 and v2 connect in one linehere i attached picture about motor terminal in star position. In tefc motors interior heat losses are dissipated indirectly through enclosure fins mostly by forced air convection. The three end terminals are connected together to form a star connection.
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. Also these motors have either six or nine leads. The three ends of three phase windings are permanently connected to these slip rings. As its name indicates three phase slip ring induction motor consists of slip rings connected on the same shaft as that of the rotor.
