A three phase induction motor has a simple design inherently high starting torque and high efficiency. Many motors can be wired for a high and low voltage and for either delta or wye sometimes called y or star wiring.
Why Wye Why Delta Pumps Amp Systems
3 phase motor wiring high low. L1 to t1 l2 to t2 l3 to t3 t4 to t7 t5 to t8 and t6. Such motors are applied in industry for many applications. These tips can be used on most electric motor brands such as weg baldor. I am trying to understand the differances between high 3 lines of 220 and low 3 lines of 110 if that is in fact an accurate description. 3 phase motor wiring diagram 9 leads collections of amazing baldor electric motor wiring diagram motors 10 3 wiring. Appreciate your help i think i understand now though.
3 phase wire diagram daytonva150. On a 12 wire motor wired for high voltage ie 480v 10t 11t and 12t must be connected together but not connected to anything else. The nameplate will specify the motor voltages and may give specific wiring information. The 3 phase motor is a rugged piece of equipment but as with everything man made there comes a time when this beautiful piece of machinery fails either due to old age misapplication mal operation or. Although these systems may seem intimidating at first a walkthrough on 3 phase wiring for dummies will help clarify the whole situation. Connect 4 to 7 5 to 8 and 6 to 9.
Wire the motor for the appropriate voltage to which you are connecting the motor. A three phase motor is more efficient than a single phase motor because of the peculiarities of alternating current ac. The w2u2v2 terminal set is the star side of the 3 phase motor while the u1viw1 is the delta side of the motor connected to the supply voltage. A motor has a nameplate wiring diagram as shown below. 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. A three phase motor is more compact and less costly than a single phase motor of the same voltage class and rating and single phase ac motors above 10 hp 75 kw are uncommon.
The other 9 wires would be connected as in a 9 wire motor note in a 9 wire motor the equivalent of t10 t11 and t12 are internally connected together. Diagram is wye with 9 leads. Examine the motor nameplate for wiring information. Select the correct connection of the leads where connected to the available 208 3 phase branch circuit so its a 120208 3 phase 4 wire wye system correct. Different regions may use different voltages. Three phase systems are extremely common in industrial and commercial settings.
And to get 208 i just wire it in series correct. In this video jamie shows you how to read a wiring diagram and the basics of hooking up an electric air compressor motor. 3 phase high and low voltages 08152010 921 am one thing the i thought of but forgot to mention above was that motor manufacturers typically wire their motors to support multiple voltages to make it easier to build just one design for multiple users. They can also be found in large residential complexes and appliances requiring a large amount of power.
