Is there a way to determine the power wire for a window fan motor?

[John]

Greetings:

I took a motor out of window exhaust / ventilation fan, which
circuitry can control speed, thermostat and rotation direction
(exhaust or ventilation). The motor has 6 wires 2 black, gray, red,
white and brown. WHT - BRN measures 100ohm, RED - GRY measures
290ohm, the rest of the wire has Mohm resistance. I can hear the
motor noise when hooking 115VAC from an outlet directly to WHT - BRN
and RED - GRY. However, the fan doesn't rotate. Am I missing
something?

Any suggestion and help is greatly appreciated.

Maybe it is a motor with condenzator(black-black).If soo, white and red go
to one wire, brown and black another wire, and another black go to grey.
