3 Phase Motor Change From 440 V To 220 V With Diagram
3 phase motor wiring u1 v1 w1. For a 3 phase motor 3 of the wires would be connected together and also connected to neutral if its a star configuration more commonly called a wye. While energized it read. Clearly my understanding is wrong from what. Two wire bundleslegs coming out of the motor casing leg 1 has u1u5 v1v5w1w5 leg 2 has u2 u6v2 v6 w2 w6 placard on motor. Connect u2 v2 and w2 to this common point. Take u1 with v1 and v2 with w2 and w1 with u2 as per drawing will it affect motor rotation power phase or what the effect this wiring will cause motor.
The af and ambz models are furnished with three phase brake coils with a separate terminal block in the connection box to power the brake. L1 goes between u1 and u2 i dont think so from recent experience but my understanding of 3 phase motors would have each winding as a single phase and the motor rotor chases each winding in turn. Connect the other 3 wires u1 v1 w1 to your 3 input phases. It is important to note that if the motor and brake coil are to be wired together to operate or stop at the same time the power should be brought to the motor block first and then connected to the brake coil to avoid the inrush current of the motor being. How do you know if the copper links between u1 v1 w1 and u2 v2 w2 on a dol motor are to be installed vertical or horizontal. If the motor turns the wrong way swap any 2 of these.
On a star delta system is there ever a time when a single phase might go between a single winding eg. Ms three phase motors.
