3 Phase Motor Connections U V W. That being said there is a wide range of different motors and what you have on hand can be completely different. U and v without a w represent power where it s connected to a piece of equipment like a motor in a single phase system.

The high voltage hv terminals have upper case letters e g. For three phase motors connection type is either star y or delta ac motor winding continuity test using a multimeter check the continuity of motor winding from phase to phase u to v v to w w to u each phase to phase must have a continuity if winding is ok. L1 l2 l3 are connected to the bottom row of terminals.
U v and w refer to that part of a wiring diagram where equipment is connected to a 3 phase load.
U v and w refer to that part of a wiring diagram where equipment is connected to a 3 phase load. The new location only has low voltage 208 3ph. A three phase motor must be wired based on the diagram on the faceplate. Make sure that the voltage you will be supplying to your motor matches the specifications on the faceplate.
