Hi All:

I have a Delta/Baldor 2hp/1ph motor from a table saw. Brought it to a motor shop and they wanted an ungodly sum to clean, replace capacitor/starter/points on the motor and reassemble. Got it back after diagnostic. I'm mechanically inclined but never have done electronics. Is this something that can be done by a diy? He said the windings look good..

Replacing the capacitor is normally pretty simple, the start switch can be done, but it involves disassembly of the motor. I've done them, but I've also run across one that was permanently attached, and fixing it was impractical. Take it apart and take a look is the best advice I can give you.

What about the points? Can they be soldered on and that's it? Also, which is the starter and which is capacitor? Thanks...

[JohnWill]

The capacitor is the Aerovox can, note that it says 12uf 370V 60Hz. I'd start by dressing up the points with a contact file or very fine emery paper and see if they can't be saved. They're a lot harder to find than the cap. If you can find them, they are indeed just soldered on. Does the motor itself have a nameplate, maybe you can find the parts that way.

Baldor is a pretty rugged motor.

How much do they want to fix it??

I have bought them for air compressors and I suspect the costs would be similar.

Sometimes it is cheaper to replace. That depends on the quality of the replacement and the hours of usage. If you buy a cheap replacement and use it a lot you will be disappointed.

How old is this motor??

it dates from early 70's. Motor shop wanted 160 for diag and 320 for repair. Paid the diag and got it. Another shop threw me a number of 200 to fix. Should I get other larger motor or try to fix myself?

If it is that old............. Replace it.

If you get me some specs on it. everything on the name plate.

I can tell you better if it is worth it to fix but based on the HP I seriously doubt it. Looks like those prices were a rewind and full rebuild. not worth it. IMO

As far as replacing a motor with another, there are some keys items that must match.

1. Frame
2. Voltage
3. RPM

Frame details include shaft size, length, and center distance from mounting feet. If this is a c-face motor (which most fan motors are) the mounting would be the bolt pattern and flange lip of the C-face mounting.

Volts details are indicated by either AC or DC volts(Yours sounds as if it is a 115vac)

RPM- This must match. The fan will not work properly if it is a slower rpm. Also, there may be more damage done if the RPM is too fast.

Remember Frame, Volts, and RPM

For my motors, I just do a web search, it's pretty easy to find the exact size motor with the proper speed. The ones I found had a universal mounting kit, but they happened to fit my fan housings without using their kit anyway.
