G E Motor Reversing

Post by redleg »

EDIT: I have added a PDF for a 1 1/8 HP G.E. Motor Model 5KC37PN186A after the 3/4hp motor on 7/19/2021


Bill Mayo showed a couple pictures of reversing a G E Motor in an Emerson motor thread in 2014. viewtopic.php?t=14341

My question is where did he hook the leads in from the power cord. I have my 3/4 hp G E motor back together after separating the run and start wires and am waiting on a DPDT switch.

I reversed an A. O. Smith 1 1/8 hp and that turned out great. Thanks to joshh for the AO Smith thread viewtopic.php?f=10&t=12664 and benmcn for the pdf version viewtopic.php?p=266179#p266179

This may add to the confusion, but the power attaches at term 5 junction and the run winding/capacitor junction.

This illustrates dual voltage wiring.

Thanks JPG for getting me headed in the right direction. The 5 was under the metal strap that holds the coil and the relay to the motor. Confused I guess!
The 5 is on the relay

It does run forward and reverse.

Some other pictures along the way.

The red wire is not attached to the relay.  Optical illusion.

I will be changing the length of the way and bench tubes as soon as I get a chance. I bought this Shopsmith because I needed the legs and casters for another unit. When I found out it had a G E motor I decided to try the reverse setup. The sanding disk and grinder don't need the reverse just had to put something on it.
