Motor help

[Strahan]

Guys looking for a wiring diagram for a Baldor single phase 115V, .33HP motor. This motor is capacitor start SER NO. B0609211379, SPEC NO. 25E340W183G1. I visited baldor's site with no luck. The motor has no diagram with it the capacitor at the time I looked at the motor was connected across the two black leads coming from the motor. There are two leads left a blue lead and a green with yellow tracer (ground). Just wondering where I hook my hot and neutral to. Thanks in advance for any help.

I would sign up at baldor, it seems all their information is behind the firewall.

An example of this is they say see "connection diagram" for motor in the installation guide, welp that phrase is not available on the open side of the any web page.

The main site is not very friendly, I couldn't find a 1/3 motor there, the west coast site in Santa Fe Springs CA,
seems a little more friendly, here and the page in-front of that is here

If that doesn't work, You'll need to find the oldest salesperson that's be there since the second day the doors opened,
and talk to them. You might ask also about the logic of there numbers, how they are grouped and the meaning behind the
sequences of the numbers and letters. Of course that might all be explained behind their firewall.

Frankly, I think you only gave the CAP. number, just an assumption.

There's no orginal construction drawings or spec's on the motor as part of the assembly?

Hope that helps.

Thanks for your help Cadpoint, I'll give it a try

Ok I searched the sites with no luck. I'm probably missing something here. My fellow co-worker is going to bring the motor in for me to look at and probably take apart, but if anyone has any idea/experience with this configuration I would appreciate the help. Baldor capacitor run or start he's telling me two black leads coming out of the motor are connected to a capacitor. Two remaining leads are blue and a green with yellow tracer. Immediately I'm thinking green with yellow tracer is a ground, but what is blue in a motor? I always assume DC when I see blue obviously that's not the case here.

Does this motor have the typical wiring compartment with several terminals in it, or are wires the only connections?

The motor has no spade connections just wires brought out of the motor. I should have the motor to look at in the next hour or so. Thanks

I can't find your motor by spec # it is possible it is an OEM built for some other equipment manufacturer. I can find other .33 hp motors and wiring schematics for them. Try looking for one with as many specs as possible the same as the motor that you have and you will probably have a schematic that is the same or very close to what you have.

You need to know if single or dual voltage, if there is internal thermal protection, what type of motor such as PSC, capacitor start, capacitor start - capacitor run, and possibly speed.

Even if wire colors don't match the schematic is probably the same as what you have. Most of the motor types have the same wiring diagram for the same features colors sometimes change from one to another but if your leads have numbers they are pretty consistant through all motor manufacturers.

We use a lot of Bodine motors in the cinema industry and they have similar lead configurations. Which I think is a standard lead marking system.

The hookup with the leads as you described is :

Black to cap
Other black to cap
Blue is line neutral
Green/yellow is ground.

Connect the hot to either of the black leads on the cap...and IIRC to reverse motor rotation switch the hot to the other black cap lead.

I cannot promise that your motor is the same, but the odds are that it will work for you.

As a test, hook up the motor as I described, using an inline slo-blow fuse rated at 125% of nameplate current. Apply power for a few seconds and if the motor starts without loud buzzing or blowing the fuse, then you can safely re-apply power and let the motor run for a few minutes and check for any signs of overheating.

Oh, and DO NOT take the motor apart!! You have to make sure the bearings are shimmed properly and the rotor is centered in the stator assembly or you will damage the motor.
