I've just recieved my 2.5hp treadmill motor and 130vdc motor control from surplus center of Lincoln NB. The motor has a thermal shut down mechanism in it. The system trips at 100 degrees opening the circuit (in-line component). I want to incorperate this into my controller. My question is do I put the shut down mechanism on the AC or the DC side? does it make a difference?
thanks for any help

Usually these devices are not used to interrupt motor power directly, but to indicate to the controlling device, drive enable , e-stop circuit etc, which in turn shut the main power off.

What item number was that motor? I just ordered this. http://www.surpluscenter.com/item.as...item=10-1783-A
Is yours the same?

I've got the 11-2449 controller from the same site. I'll be interested to see how you attach your motor, and the fan. I think this is gonna be a common issue with these machines. We should both post pics!
Also, think we'll feel the extra HP?

I just got my new motor/controller combination working again. As I see it, the key to getting this thing working properly again, after attaining the new components from SurplusCenter.com is getting a new 5K Potentiometer from Radioshack and then getting replacement fuses.

Mine now works beautifully, all I have to do is connect the motor to my mill and I'm good. The important part is that this conversion works. So buying expensive replacements from LMS, ($275.00 + shipping for a new motor and circuit board compared to $40.00 at SC) will no longer be necessary.

Now what about that fan?

Do you mind me asking some questions:
what you are machining?
The size of pulleys on motor and on spindle and belt?
and a couple of pictures of the set up?
Thanks in advance
