I acquired a blower assembly from an old air handling system, with the intention of using it as an exhaust fan in my workshop.
It came as an assembled unit of blower and motor on a subframe. The wires had been cut prior to my arrival.
I have Googled "7-wire motor," "AC motor wiring," "brushless AC motor wiring," and many more ways of trying to describe what I have in-hand. I have been unsuccessful in finding useful information about how to wire this up.
I have found a couple of things that appeared to describe how to figure out what wires do what - one of which takes me through testing for continuity and says I should find two separate groups. I don't.
ALL wires have continuity to each other. Verified by using a 12v battery and a light bulb, + to each wire and - to others for each of the colors. Bulb lights up every which way.
Motor label info: 493 (probably a part number i guess) 1PHASE TYPE CA0514D-R SANSO POLES 4 OUTPUT 85 W VOLT 220-240 V HZ 50 07.08.28 KC
Wires: Black, Red, Yellow, Blue, Orange, Grey, White
What I want to do:
1) Make it run, using any built-in speed differences that may be a part of the existing setup.
2) Alternately, just make it run, full on.
I sorta thought this would just be simple, but I guess not. Don't want to feed power to any wires until I can tell what is what. Need help. Below are pics of the lot.
