3 phase motor wiring diagram 6 wire. Make sure that the voltage you will be supplying to your motor matches the specifications on the faceplate. Capacitor motor single phase wiring diagrams always use wiring diagram supplied on motor nameplate. Six wire three phase electric motors are dual voltage motors. If there is a neutral wire in the conduit or cable supplying the motor it is unused for the motors three phase wiring. How to wire a three phase motor. 480 vac wye connection step 1 remove all electrical power.
6 lead 3 phase motor wiring diagram wiring library 3 phase 6 lead motor wiring diagram wiring diagram consists of numerous in depth illustrations that present the link of various items. Three phase motors are more efficient than single phase motors and are commonly found in applications requiring more than 75 horsepower. Although the national electric code does not specify specific conductor colors for three phase current it is common to use black red and blue wires to identify lines l1 l2 and l3 respectively. 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. The motor will supply the same amount of power but with a different load amperage. Wiring diagram 6 lead 3 phase 480 volt motor wiring library 3 phase motor wiring diagram 6 wire wiring diagram contains the two examples 3 phase motor wiring diagram 12 leads.
That being said there is a wide range of different motors and what you have on hand can be completely different. Multi speed 3 phase motor 3 speeds 1 direction power control diagrams one line diagram of simple contactor circuit. Three phase 4 wire system is most commonly used connection that consists of three phase conductors and one neutral conductor. Turn off the. June 15 2020 wiring diagram by anna r. The supply voltage is either 240 volts alternating current vac or 480 vac.
A three phase motor must be wired based on the diagram on the faceplate. 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. A 9 wire motor can only be connected in a wye configuration whereas a 12 wire motor can be connected in either a wye or delta configuration. February 10 2019 april 12 2020 wiring diagram by anna r. How the wires are interconnected dictates the voltage being supplied to the motor. Both 9 wire and 12 wire motors can be connected for high or low voltage operation.
In this three phase wiring lighting small appliance loads and receptacles are often connected between phase and neutral while larger equipments such as air conditioners and electric heaters are connected between two phases ie phase to phase. Mostly three phase 4 wire star connection is preferred for connecting both single phase and three phase loads efficiently.
