Dual Voltage Motor Electrical Engineering Centre
Six wire threephase electric motors are dual voltage motors How the wires are interconnected dictates the voltage being supplied to the motor The supply voltage is either 240 volts alternating current (VAC) or 480 VAC The motor will supply the same amount of power, but with a different load amperage The higher the voltage, the lower the amperageFor delta and wye 9lead motors In addition, the 12lead motor requires connecting wirenut 10, 11, and 12 together The following diagram illustrates these connections graphically Wye connected 12lead wiring diagram Wye connected 12lead motors differ from 9lead threephase dualvoltage motors in that none
