motor leads i.d.

motor leads i.d.

(OP)

what are the white wires for?? thank you!

RE: motor leads i.d.

Temp sensor or switch. Likely an RTD sensor.

Got a close up picture of the label/plate?

Thanks

RE: motor leads i.d.

"OVER TEMP PROT 2" on the nameplate may be a clue.
This looks like a single voltage 4 lead motor.

The connection diagram that is not readable in your picture probably says something like:
"Single phase Motor Lead Connections
Connected for Counter - Clockwise Rotation
To Reverse Rotation Interchange Leads $ and %"
Note: "Volts 208/230" on the nameplate refers to the voltage tolerance range, not dual voltages.

RE: motor leads i.d.

I would agree with you bill on the "Motor Protection 2" and that's why I wanted us to see the nameplate.


helloman22; Use an ohm meter and measure across those two leads.
While you're at it make sure they are not common with any of the big yellow leads at the same time.

Let us know what you get for resistance between those two white leads.

I'd expect for an RTD you'd see something around 110ohms or 1,100ohms. If instead it's a thermistor I'd expect something over 10,000ohms but under 100,000.

Or I'd get 150 ohms if its a brake coil or a full continuity if it's an NC thermal overload protection switch!
