3 phase electric motor connection. When a motor is part of a machine the ground wire may be connected to the machine frame rather than the motor frame. This video explains how to wire a three phase induction motor to an external electricity source. This edition of easa internal connection diagrams contains significantly more connections than the previous version 1982 as well as improved templates for drawing.
A three phase motor must be wired based on the diagram on the faceplate. It also shows the difference between delta and star connecti. 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 motors have only three hot power wires connected to the windings. Internal connection diagrams for three phase electric motors. Make sure that the voltage you will be supplying to your motor matches the specifications on the faceplate.
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. Easa members can download a pdf of internal connection diagrams for free. In this video explained how we can do connection of three phase motor starter.
In the united states for low voltage motors below 600v you can expect either 230v or 460v. An earth ground wire should be connected to the frame of the motor but sometimes that is not done.
