Double use of DC Controller?

I'm fixing to set up a dc disc sander and even though I have a controller for the motor I was thinking how convenient it would be to run the disc sander off the controller that my wilton is hooked up to. It would be simple enough to rig a junction box and run the power feed from the controller to the box and have the supply lines to both motors going out from the box. Just hook the positive wire from the controller to a single pole double throw switch and splice the negatives together. Put the switch on the tool you want to run and turn on the controller.
Sound reasonable??
 
Hey Buddy,

That's what I have. However, I'm a little paranoid. I used a double pull, double throw - the motors are totally isolated. Also the motors are identical so there was no readjusting the speeds or anything. Just turn it off, flip the switch, turn it back on. I happy with the setup.

Hmmm, I didn't think about the trimpots Steve, thanks for mentioning that!!!
The second motor I want to hook up is a 90 volt and the one thats on it now is 180 so I probably shouldn't put the two together. I'll just use the controller I have for the disc sander for now and maybe pick up another 180 volt motor later.
 
I asked the same question a while back on one forum (don't remember when or where) and got nods all around, but one thing I didn't ask is if different horsepowered motors could be hooked up to the same controller without any damage?
I have a 2HP motor on my KMG and have a 1.5HP I would like to hook up as a disc sander, but don't know if there would be any problems. They are both the same voltage and everything else, just slightly different HP.
Thoughts?
Thanks,

Wapiti,

If you can run both motors without manually re-configuring the controller (and I bet you can)- I don't see any problem. IF you turn it off before switching. The controllers keep track of 'stuff' while they are on - monitoring voltage and load, etc. But (at least on mine) there is no 'memory' after the power is off. So it starts afresh every time it powers up.

Mine has a 'reset' switch you can use to do this without switching off. The book says OFF/ON and RESET perform the same function. I don't use that, I just switch it off.

There are 'tuning' pots for min/max speed and acceleration, but I'll be you can find settings that will work fine for both motors.

Hope that helps,

Steve
 
I have another use for mine, not only do I run my mini-mill & lathe with it but I also use it for my anodizing of Ti, talk about your range of colors. I probably got $10.00 in my anodizer. :D
