110 Volt 3 Phase Wiring Diagram Wiring Diagram
Dual voltage 3 phase motor wiring. There are three pairs i was able to identify using an ohmmeter no labels or tags on the wires. Connect 3 5 and 9 to l3. Many 3 phase motors allow for two possible line voltages for example 230460. To avoid confusion obtain a pocket motor wiring guide and refer to it while performing the work. This is contrary to every other dual voltage three phase motor ive seen. After cleaning the wiring up i believe it is a single phase dual voltage motor.
I recently purchased a 34hp six pole emerson three phase motor on ebay. Split phase motor dual voltage reversible rotation capacitor motor single phase wiring diagrams always use wiring diagram supplied on motor nameplate. 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. For both low and high voltage the same wiring configuration is shown. W2 cj2 ui vi wi w2 cj2 ui vi wi a cow voltage y high voltage z t4 til t12 10 til t4 t5 ali l2 t12 ti blu t2 wht t3org t4 yel t5 blk t6 gry t7 pnk. Connect 4 to 7 5 to 8 and 6 to 9.
Two wiring configurations wye and delta indicate the wiring methods for three phase motors. A three phase motor is more efficient than a single phase motor because of the peculiarities of alternating current ac. 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. They can also be found in large residential complexes and appliances requiring a large amount of power. Connect 2 4 and 8 to l2. Number is 6123 the wiring connections on the motor label are confusing.
Different regions may use different voltages. Three phase systems are extremely common in industrial and commercial settings. 220 240 vac 3 phase. These instructions cover a dual voltage three phase motor the most common type. For the delta start dual voltage nine lead motor on the lower voltage connect 1 6 and 7 to l1. I have six leads three yellow three black.
Although these systems may seem intimidating at first a walkthrough on 3 phase wiring for dummies will help clarify the whole situation. What is dual voltage for electric motor. For the higher voltage connect 1 to l1 2 to l2 and 3 to l3. 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. 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. I am trying to understand how the different wiring is changing the way the windings get current.
Single phase dual voltage six wire motor wiring i have a sebastian lathe with what i originally thought was a three phase motor.
