I picked-up a P/n: 3352287 3-speed motor off eBay, and would like to use it to run a meat grinder.  Would any of you fellas happen to know what wires on the harness I have to provide juice to run at the 3 different speeds (1725/1140/850)?

EDIT: I'm mostly only interested in the 1725RPM mode, but would like information on the other speeds for possible use later.

I did also find a wiring diagram for a Neptune model that uses this motor, but I'm not sure I understand how each "P" portion interacts. :)

Thanks!

I wouldn't advise modifing a meat grinder. You would need a safety stop/disconnect accessible to the operator.

You would need an ON/OFF switch and a 3 position switch for the speeds (4P, 6P, 8P) and a push to start button (4P AUX) for the start switch in series with a AC start capacitor. 324-389MFD 110V AC

Thanks Reg; I realize that in todays blameless society, such disclaimers are necessary.  I am a resposible adult and understand that meat grinders will grind my appendages just as easily as anything else. ;)

The motor came supplied with its starting capacitor, so a replacement will not be necessary.  I've got a factory harness with leg wires  that plugs into the motor switch (red - FSP 62850 on top of the motor).  I'll forgo the other speeds for simplicity and only need information on how to energize the (8P) section and how to start it.

No ideas guys/gals?  Basically, if I wanted to test this motor to see if it works (by giving it current), how would I do that?

white & yellow wires go to neutral

blue (hi-speed) goes to switched power

black goes through capacitor and through start switch to power

Thanks again Reg!  So, the field winding needs to be energized (blue wire) before the start circuit is energized?  Then, once the motor is running, the start circuit can be disconnected?  Or is the start circuit automatically disconnected by the centrifugal switch?

the start winding would be automatically disconnected by the centrifugal switch if it's part of the motor. Some motors it's a separate switch mounted on the motor....

ooh.. I see your message that it came with the switch.

OK, neutral goes to white & yellow wires.

switched power goes to blue (hi-speed) 


& through capacitor to the centrifugal switch (Red connection).

Thanks again for all your help, Reg!  The capacitor popped, but I think it was faulty (internal short). I'll have to pick-up a new one from the surplus center.  The motor did run though. :)

OK, make sure it's an AC start capacitor of similar ratings

Reg,

I just picked up a junk Whirlpool washer that was set on the curb for Spring Cleanup.  I salvaged the motor (the same one in this thread)  for a project and wired it just as you said earlier in this thread.  The motor works great.  I'm just wondering... if blue is the high speed, what wire is the low speed one.  The only other color wire on the harness is orange, and it doesn't appear that there is a wire that connects to that pin in the plug and goes down into the motor like the blue one did.  The only other wires that are unused that go from the plug down into the motor are brown and black.  Are these different speeds (similar to the blue) also?

Thanks,

Gene

if it's the same motor:

as shown in the OP's first message PDF:

High speed = Blue

Med speed = White / Violet

Low speed = White / Orange

 

Start = Black

Start = yellow

Neutral = White
