sync motor wiring question
Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <FutureT-at-aol-dot-com>
All,
I have a hysteresis sync motor here that I'm not sure how to
wire up. I realize that these motors always start in a different
phase position and are not good for sync rotary gaps. Nevertheless,
I want to do some tests.
The motor is made by Siemon Mgf Company, of Wayne ILL.
The motor is rather old. I didn't try contacting the company.
Part # 8274, serial # 122, 115VAC, 60 cycle, 0.4Amp, single
phase. It uses a 3.5uF run cap.
The motor has 5 wires, none of which are a ground wire.
I measured the resistances between pairs:
ohms
white to yellow = 91
white to black 210
white to red 210
white to blue 180
yellow to black 300
yellow to red 301
yellow to blue 270
black to red 425
black to blue 390
red to blue 390
Maybe it's a two speed motor? The label mentions nothing
about speed. Anyone have any idea how to wire this up?
Thanks,
John
