centrifugal start switch equipped motor. It was made by New England
Gear Works, a division of Robbins and Myers, and the wiring info is no
longer available. The windings fill all the slots in the stator
completely. There are two windings. One measures 8.5 ohms and the
other 36 ohms. I believe the 8.5 ohm winding is the run winding.
Connecting the windings in parallel will start the motor. Reversing
the way the windings are paralleled will reverse rotation. The motor
runs rough then until either winding is disconnected. I have tried
using an 8 mfd capacitor on either winding and leaving the winding
connected. The motor runs less rough this way than without the cap.
The motor runs hot when running on either one or both windings. It's a
40 rpm gear motor with significant torque, so much so that I can't
tell if it has more torque running on the 8.5 ohm winding than the 36
ohm winding. So, any suggestions which winding is the run one?
