Dual voltage 3 phase 9 lead wye motor connections 2 duration. When a motors power supply is brought in from three wires instead of just one with the power delivery cycling through each of these in sequence hence the a part of ac it permits an effective power level that is 3 times higher about 1728 times higher than a.

3 phase dual voltage motor wiring diagram. The first step is to figure out the voltage of your phases. Three phase see below single voltage. Below figure is a electric motor name plate that have a dual voltageif we can seeit have two connection motor terminal for two voltage for power supply. With the main windings connected in parallel the line voltage is usually 240. 220 240 vac 3 phase. 380 415 vac 3 phase.
Many 3 phase motors allow for two possible line voltages for example 230460. These instructions cover a dual voltage three phase motor the most common type. For specific leeson motor connections go to their website and input the leeson catalog in the review box you will find connection data dimensions name plate data etc. This motor has two identical main windings arranged for either series or parallel connections. Dual voltage motors how they work and wiring them without the wire labels. Always use wiring diagram supplied on motor nameplate for motors with thermal protection single voltage single rotation single voltage reversible rotation.
I am trying to understand how the different wiring is changing the way the windings get current. Split phase motor dual voltage reversible rotation capacitor motor single phase wiring diagrams always use wiring diagram supplied on motor nameplate. Split phase single value capacitor electric motor dual voltage type. The voltage cycle of each line lags its predecessor by 120 degrees l2 reaches its peak voltage after l1 and l3 reaches its peak voltage after l2. A three phase motor is more efficient than a single phase motor because of the peculiarities of alternating current ac. In the united states for low voltage motors below 600v you can expect either 230v or 460v.
A three phase motor must be wired based on the diagram on the faceplate. Split phase single value capacitor electric motor dual voltage type. I would guess that wiring for high voltage the motor would use all the windings and when wiring for low voltage it would only utilize half the windings. W2 cj2 ui vi wi. This video will walk you through the standard winding terminal designations proper wiring connections and expected winding voltages for a dual voltage 3 phase 9 lead wye motor. Two wiring configurations wye and delta indicate the wiring methods for three phase motors.
What is dual voltage for electric motor. Electric motor wire marking connections.
