This is for a wye motor. Split phase motor dual voltage reversible rotation capacitor motor single phase wiring diagrams always use wiring diagram supplied on motor nameplate. Dual voltage 3 phase 9 lead wye motor connections 2 duration.
Connecting a 3 phase motor with 1 phase power with diagram duration. Connect motor leads 9 and 3 with the blue l3 conductor. L1 to t1 l2 to t2 l3 to t3 t4 to t7 t5 to t8 and t6. 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. Although these systems may seem intimidating at first a walkthrough on 3 phase wiring for dummies will help clarify the whole situation. Connect motor leads 8 and 2 with the red l2 conductor.
Pete vree 16304 views. They can also be found in large residential complexes and appliances requiring a large amount of power. Single phase electric motor wiring tutorial. Three phase systems are extremely common in industrial and commercial settings. 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. 3 phase motor wiring diagram 12 leads sample how to check polarity of each winding in 3 phase motor.
Different regions may use different voltages. Im just trying to better understand how to know if it is high or low voltage when wiring a motor. Connect motor leads 4 5 and 6 together. Connect motor leads 7 and 1 with the black l1 conductor. But this is a wye system so i assume its 120208 so for wiring these things up do i say. 3 phase low voltage motor wiring diagram i asked what the voltage was a high limit control a low water cutoff as a safety device and a thermostat setting the comfort level.
3 phase 6 lead motor wiring diagram elegant awesome 12 lead 3 phase. Three phase motors also vibrate less and hence last longer than single phase motors of the same power used under the same conditions. Make the connections for low voltage 230 volt wiring. If i have a question that asks how to wire up a motor that has available leads of 208 volt 3 phase. A three phase motor is more efficient than a single phase motor because of the peculiarities of alternating current ac. 208 is low voltage correct.
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.
