5HP DC Motor wanted for '73 10EE

[dieseldog105]

Hey all, Looking for good used 5hp motor for my '73. All the guts are original in my machine and in working order. It sits around alot, ran great one day and poof. Now they say it needs a rewind. Let me know what you have.

For your '73 what? 10EE? Something else? What kind of motor? DC motor?

it has 8 wires coming out of it.
whats the going rate for a rewind?

If you decide to install a Vfd I have a 3hp inverter duty motor with the gearbox mated to it.It was on a 68 ee I had a few years back.It was in pretty rough shape mechanically when I got it,but I changed it over anyway.The motor and gearbox are fine.This was the 4000 rpm model though.The motor is 3300 rpm 220 3 phase.

Try this guy: Tas Iron Ltd. Ask for Tim. He's a machinery rebuilder near Cleveland and usually has 10EE motors to sell.

Motor rewinding is an expensive ordeal. I still don't know what "motor" you are talking about. IN a MG setup there is a DC spindle drive motor, an AC 3-Phase motor driving an inline DC generator and belt driven "exciter" DC generator. In my experience the going rates to rewind / rebuild a motor is probably $2-3K. Still WAY NOT enough information to make any sensible conclusions. So I say again, a MG 10EE has 1 DC Spindle motor, 1 AC 3-phase generator drive motor, and 2 DC generators.

Someone correct me if I am wrong, a 5HP DC spindle drive motor would not have 8 wires coming out of it......sounds more like the MG unit?

He likely has a modular drive machine with 5hp GE Kinematic spindle motor, those machines generally only have 2 motors- spindle motor and coolant motor, there are no Generators in Modular drive machines.


The spindle motor will likely have leads A1/A2 for the Armature, S1/S2 for the Series Field and F1/F2/F3/F4 for the Shunt Field, usually connected in pairs because the Shunt field is 115/230V.

Colt45 is correct. Thanks Cal, Tim's got good used ones for 500. The local shop here said 2100 for a twist. But, I think Tim sold me on his ac conversion setup. J/k I'd never go tubeless... Thanks again!

 

[Cal Haines]

What does Tim charge for his conversion?

By the way, For Monarch 10ee Lathe has nice solid state modules that would also make you tubeless with the original DC drive.

This is good advice!
Those solid state modules and the electronic tube replacements work perfectly on my '77 modular.

Got it in one.

It's the dual-Voltage field option that confuses.
Older ones didn't necessarily HAVE that, or folks overlook it if they DO have.

OEM Module drive is easily put-right with Scissio's goods.
Solid State altogether DC Drives also work.

No NEED of a VFD downgrade and the extra work of gearbox integration and DIY mounting "engineering".

KinaMatics can be had. Or Louis-Allis.

Run what you got!

I have a 5HP GE motor that is gathering dust. It came from a 70's modular that Al Sharon converted to 3-phase. I would sell it for $300 plus shipping. Price includes palletizing/crating. I have another 5HP motor available as well.

I'm interested in the motor rimcanyon. I cant figure out the messages.
