how does wiring a motor delta or wye Change if it can handle 480v or 240v supply

Question

you can run some motors on 480 or 240 by changing the configuration in the peckerhead to form a delta or wye/star connection. How does that work? Seems like voltage goes through the same coils would need the same voltage. It’s not like there is a nuetral in the middle of the star

Answer 1

Motors can have additional coils, wired in series or parallel. Wiring delta or wye(star) configuration determines if it’s series(higher V) or parallel (lower V).
