Frankenmotor?

[retiredsoldier919]

I saw this Emerson motor and wondered if it would be possible to take the shaft and rotor from the Shopsmith Emerson 1 1/8 hp motor and put it into this unit. The though being that you take what is special about the Shopsmith version and make it work in a different motor. Has anyone done this? I know mounting it would require additional work, but doesn't seem impossible.

Maybe, if I read more of your postings, I would not have to ask this question. What is wrong with the Emerson motor that you already have?

Then the real question, yours. Can you reconfigure the new motor to make it compatible with your Mark V. Probably not but because the Emerson in the Mark V is a special build for Shopsmith. Emerson will not even talk to you about motor specifications on that motor, let alone sell parts to you to repair it.

That said, I am not certain that you could not mix parts from other Emerson Mark V motors to create one good one.

My motor is unable to run under a load. So I'm just thinking of other fixes outside of putting in another Emerson 1 1/8 motor. I may be jumping the gun but I like to look ahead in case this motor is toast.

I think you will have a better idea on this after the shop looks at your motor, I haven't been following really close but I think that was going to be your next step.

I can't complain about any of the motors I have from shopsmith. They are all running or were running when I took them out of service. I upgraded my 1976 machine to a powerpro not long ago and kept the motor as a spare hoping to never need it but none the less there is some security to that. I should really take it apart and put in new bearings and clean it up really good but haven't done so yet.

I have a couple more headstocks/machines all of which are still working and dating back to the late 70's until about 1980. So I have to conclude that lasting 36 or more years is not bad for a motor.

Shopsmith sells them for $359 which sounds high but my brother had his non-shopsmith saw motor go out and they wanted $400 for a replacement. Shopsmith has deals on the motors once in a while so while I don't normally look at them they must give at least some discount on that price during the sales.

The other option is used off ebay or wherever. Of course you never know how they are going to fair but you might save some money or end up with a dud.

Yes, my next stop was a local electrical motor shop. However, one of our esteemed members has graciously offered to look at it. So I am going to see if he finds the problem. If the motor turns out to be burned out or too hard to repair, I'll look into a replacement. I do like what I've seen in the DC motor threads on these forums.

David stopped by my shop with his headstock today. We removed the motor and tested it. It would only rotate at a few RPMs and I am sure it would have tripped the breaker if not turned off. We disassembled the motor and took ohm readings. The run windings was only .25 ohms and the start windings was 5 ohms. You could see that the headstock had never been operated since it was new. No sawdust in the headstock (510) and no belt marks on the sheaves. I believe this was a faulty motor from the factory. We installed an AO Smith motor and the headstock operated beautifully. First motor I have seen with this low an ohm reading for the run windings {1-2 ohms).

Bill got me up and running as I assumed he could. Bill also sold me, at an excellent price, some parts that I did not receive with the Shopsmith. Bill, you are a wonderful ambassador for Shopsmith, and a kind gentleman. Thanks for everything and I'm honored to have met you. Hope to see you again.
