There are three pairs i was able to identify using an ohmmeter no labels or tags on the wires. I am trying to understand how the different wiring is changing the way the windings get current.
E18 Wye 3 Phase Dual Voltage Motor Wiring Diagram Wiring
Dual voltage 3 phase motor wiring. They can also be found in large residential complexes and appliances requiring a large amount of power. For both low and high voltage the same wiring configuration is shown. 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. 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. 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. Connect 2 4 and 8 to l2.
I have six leads three yellow three black. After cleaning the wiring up i believe it is a single phase dual voltage motor. Different regions may use different voltages. 220 240 vac 3 phase. This is contrary to every other dual voltage three phase motor ive seen. Connect 4 to 7 5 to 8 and 6 to 9.
Split phase motor dual voltage reversible rotation capacitor motor single phase wiring diagrams always use wiring diagram supplied on motor nameplate. Although these systems may seem intimidating at first a walkthrough on 3 phase wiring for dummies will help clarify the whole situation. I recently purchased a 34hp six pole emerson three phase motor on ebay. 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. Single phase dual voltage six wire motor wiring i have a sebastian lathe with what i originally thought was a three phase motor. What is dual voltage for electric motor.
To avoid confusion obtain a pocket motor wiring guide and refer to it while performing the work. 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. The model numner is p63sytba 3781 the cat. Many 3 phase motors allow for two possible line voltages for example 230460. For the delta start dual voltage nine lead motor on the lower voltage connect 1 6 and 7 to l1. A three phase motor is more efficient than a single phase motor because of the peculiarities of alternating current ac.
Two wiring configurations wye and delta indicate the wiring methods for three phase motors. Number is 6123 the wiring connections on the motor label are confusing. Connect 3 5 and 9 to l3. For the higher voltage connect 1 to l1 2 to l2 and 3 to l3. These instructions cover a dual voltage three phase motor the most common type. Three phase systems are extremely common in industrial and commercial settings.
