3 Phase Motor Wiring Diagram U V W. In normative for manufacture electrical motors there exist two standards. In the united states for low voltage motors below 600v you can expect either 230v or 460v.
For example a two pole three phase motor has 6 nests 3 coils per nest and 6 leads. European countries and australia only have one voltage for low voltage 3 phase supplies so multitap windings like the 9 wire type are unnecessary in such countries. L1 l2 of course if it is single phase.
A three phase motor must be wired based on the diagram on the faceplate.
I have also seen different designations in various countries i ve worked in so ultimately these are arbitrary though u and v and w are the most common. Make sure that the voltage you will be supplying to your motor matches the specifications on the faceplate. A b c r y b u v w l1 l2 l3 and the low voltage lv terminals have lower case letters e g. U v and w refer to that part of a wiring diagram where equipment is connected to a 3 phase load.
