Cut motor rebuild

[dehrlich]

Wondering, can you send cut motors in to LHR, have them rebuilt and returned to you? I have two or three that need to be done.

If you buy a new one and then return your old one, supposedly they will give you money back ($40?) for the old one.

Not any more..

They do credit you for rebuildable parts you send in. I got a whole box full of parts I just never sent back. I'm trying to save up enough to buy a new machine with refunds from parts haha. Anyway, $185 for a new cut motor just is a little pricey for me, gonna have to really need one.

How does that work? We have been lead to believe that the rebate process for parts has been discontinued.

[normrichards]

If the cases are good (not cracked or broken) I am sure there are people on here who would be willing to buy cut motors. There are probably other parts you may be able to sell as well.

The rebate program was canceled January of 2016.

I have a cut motor from my parts machine and I'm wondering if there's a way to power on it's own. You got the white and black power wires and then the plug in for the computer. I wonder if I could just hook up the power by itself.

The square drive flex shaft fits right onto my heavy duty square drive Fordom hand piece.

[normrichards]

In order to test cut motors I have hooked the white and black directly to 110 power, it will work this way but only at one speed. Make sure the motor is clamped or held down.

[Alan Malmstrom]

So if I wire it up to a chord straight to the electrical wall outlet it will work right? I know that the small wall plug prong is the positive or white and the large prong is the negative (black).

Should that work.

I have a motor speed dial plug that I've used for other stuff would that work on the motor. I wouldn't start so fast if it is usable for that.

Yes I would secure the motor.

The Armature wearing down is the big problem... 3 sets of brushes and it pretty far gone....

I plan to try a ROCKY 30 small trim router one day as a replacement for the cut motor... Mounted above and slightly behind the machine.

**** I DO NOT KNOW IF THE SPEED DIAL PLUG WOULD WORK OR DAMAGE THE MOTOR*****

Yes I would secure the motor.

Hope that helps, not yelling but wanted to differentiate my answers from your questions.

Thanks Norm

I don't know much about motors and electric. But thanks for the info. I will try it. The speed switch that I have is the same thing they have at Harbor Freight. When I bought it the package said it was a router speed control. I think it has a 5 amp fuse in it. I'll try it and tell you if it works or not. Maybe not for a few days though.

The cut motor is the most basic AC/DC motor. If your speed control can handle the current, it will probably work fine.

I agree....

I hooked up the router speed control bot straight to the motor and it works good. The control box uses a 15 amp fuse. So I put a 15 amp microwave fuse in it that I had available. The initial speed on low is pretty fast and the motor revs up smoothly when I turn up the speed.

I'm thinking that the plug in wires that go to the computer are hooked up to some sort of speed indexer or something and don't really have to be used to run the motor.

I was going to wire a 115 VAC Relay to the Machine Motor Wires then let the Relay turn on and off the Router. I posted that once before and LHR said to NOT DO THAT....

Had not need to convert since so no progress trying....

I WOULD eliminate the machine's ability to control the speed and the machine would likely give you a CCM and go into default open loop mode speed control. I believe normally the machine is in a closed loop speed control using the speed sensor.
