Letters and numbers are used as follows. It mean terminal cooper plate w2u2 and v2 connect in one linehere i attached picture about motor terminal in star position.
How To Connect 3 Phase Motors In Star And Delta Connection
3 phase motor connections uvw. A procedure has been adopted by the iec for identifying three phase winding connections. A b c r y b u v w l1 l2 l3 and the low voltage lv terminals have lower case letters eg. 12 lead three phase motor wiring diagram schematron. If there is a neutral wire in the conduit or cable supplying the motor it is unused for the motors three phase wiring. Generally a brushless dc motor has 8 lead wires 3 phase wires and 5 hall wires and motor controller with the corresponding interfaces. They can also be found in large residential complexes and appliances requiring a large amount of power.
Three phase systems are extremely common in industrial and commercial settings. Make all wiring connections with wire nuts of the correct size for the conductors being used and the number of conductors being connected together. 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. The high voltage hv terminals have upper case letters eg. In this video ato shows you the connection and control.
A b c r y b u v w l1 l2 l3. 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. Cap it with a wire nut. From this motor nameplatewe can see it have 2 connection and 2 voltage valueif our power supply voltage is 415 vac for 3 phasewe need to setting the motor terminal in star connection. Different regions may use different voltages.
