Hi,
I posted earlier look for a solution to a chuck, it isn't quite solved yet but thats alright. I am now on a different problem/ question.

I have this contactor what is a cnc contactor and I am wondering how I use it to control the spindal motor. I am using steppers to move the tail stock and the tooling. The spindal is a DC motor out of a blower and it would be very cool if I could use this contactor some how to control the motor.
Is it something I can use with pokeys or phidgets?

Thanks for any help.

My contactor is found at what is a cnc contactor and there is a link on the page to one for sale on the page.

The contactor you show is primarily used for 3ph AC control, DC requires some special arc shields and contacts, normally you control the spindle motor through a controller of some kind? or are you operating this motor full on?
Do you need reversing feature?

I use a contactor (same brand) in my powder coating oven 220v 1phase and its really loud! I think you would burn it out trying to control a motor or drive you nuts before it burned out. At minimum get a SSR with a heat sink.

Maybe use that in conjunction with the Super PID and have it trigger the SSR...

keep the contactor to be your main power switch to the machine

The OP mentions a DC spindle, the PID is for a universal motor.
It all depends on the nature of the spindle control?

oops I miss that.

Hi,
Thanks for all your help.
I suppose I am better off just leaving things the way they are for now, I don't need to control the spindal and if I do I will just change the motor to a stepper.
I just figured I could use the contact block for something, it has been sitting around for a while now.
Al what do you mean by a "universal motor"?

Al what do you mean by a "universal motor"?

A search will show several hits, Universal motor, field in series with the armature, will run on ac/dc, rpm limited by friction.
Most hand tools, vacuum cleaners, routers.

Thanks!

So there is a chance this is a Universal motor, it came out of a blower. We used it in a playground "Ballocity" unit until a child threw a rock in it and destroyed the fan.
I will upload a few pictures to the forum along with any numbers found on the motor when I get home and settled tonight.

Again thanks for your help and time, your a very knowledgable person!

Also I may need to buy you a beer later tonight! I just noticed the option and you deserve it.

Very possible, I assume you thought it DC because of the brushes Maybe?
Thanks.

Yes the stator is a magnet and the armature is magnetized threw the brushed. I also figured the capacitor attached acts as a rectifier.

Now on to buying you that beer!
