I have an AC motor with 7 different wires connecting to it, and I'd like to identify how the windings are configured. The wires are:
- Red
- Orange
- Yellow
- Blue
- Black
- White
- Yellow+Green
What I've been able to gather so far is that:
- Yellow+Green is protective earth and connected to the motor housing and nothing else
- White is directly connected to mains neutral
- Live mains is switched directly onto Yellow, Blue, Black, or nothing to provide 4 different speed settings
- There's a capacitor across Red and Orange
These are the resistances I've measured between the different wires in Ohms:
Orange | Yellow | Blue | Black | White | |
---|---|---|---|---|---|
Red | 34 | 29 | 23 | 17.3 | 33.2 |
Orange | 28.6 | 22.6 | 16.7 | 0.3 | |
Yellow | 6.1 | 12 | 28 | ||
Blue | 6 | 22.1 | |||
Black | 16.4 |
(Note that the measurements between White and the other terminals might be slightly high. They were made from the neutral pin of the AC cord of the device for convenience, whereas everything else was measured directly on the connectors on the motor.)
Given that information, how would I go about identifying the motor's configuration?
Thanks!
