12 lead part winding motor

Part Winding. Dual voltage motors typically have split windings, but they can only be started on the lower voltage. They are NOT Wye/Delta. The auxiliary winding is also known as starting winding. * 3. The simplest and most economic way to start a three phase, squirrel cage, induction motor is with a full voltage starter. The electric motor winding definition is, windings in electric motors are wires that are placed within coils, generally enclosed around a coated flexible iron magnetic core to shape magnetic poles while strengthened with the current. Electric motor wire marking connections. The other strange thing in this point (where 3 leaads are connected together) is that one of the leads are with 6 wires, the other two leads are with 3 wires See Part 18.† MG 1-2.42 Auxiliary Devices Within Motor .
