Dual Voltage 3 Phase Motor Wiring Diagram 9 Leads. In the united states for low voltage motors below 600v you can expect either 230v or 460v. Split phase motor dual voltage reversible rotation capacitor motor single phase wiring diagrams always use wiring diagram supplied on motor nameplate.
Identifying leads of a nine lead three phase motor. The basic wiring diagram is 1 7 to one phase 2 8 to second phase 3 9 to third phase and 4 5 6 hooked together to be the external star. It is of utmost importance to firstly understand the internal wiring configuration of a 9 leads ac induction motor before doing the actual wiring connection.
In addition all three have six internal coils although their internal connections differ widely.
It shows the elements of the circuit as simplified shapes and the power as well as signal connections between the gadgets. Always use wiring diagram supplied on motor nameplate colored leads are only applicable on the new rolled steel motor lines. A three phase motor must be wired based on the diagram on the faceplate. That being said there is a wide range of different motors and what you have on hand can be completely different.
