I've got this hole drilling machine that has the control box for it. The box is bad. Trying to identify it so I can find a replacement. Any help greatly appreciated file attached picture

 

Appears to be a PWM motor controller with hall effect or other commutation pulses.?
Might be worth getting someone that is technically capable to open it up and take a look !

Thanks for the reply. I've been looking around my area which is pretty remote. Nobody that I've come across so far knows anything about it.

We ended up taking it a part. It looks to me like there was a resistor in the upper right hand corner that has blown. Idk if thus help at all but I thought I would post it.

 

Sorry, don't see it?

 

I also can't see the blown resistor but as it looks like part of the board is a switch mode power supply I think it is probably a fusable resistor on the input side of the rectifier. If I am right I don't think just repacing that resistor will fix the problem.
I think components on the primary side have failed short circuit which caused the resistor to fail.
You would need to understand what you were doing to repair a switch mode power supply as one faulty component very often causes many components to fail. If you do not identify and replace ALL of the faulty components then the components you have replaced will be destroyed again.

Usually with SMPS you do not see the large electrolytic caps? , IOW, may be a mains fed PS.
You could also look for some power Mosfets, of which could have blown.

That make sense. This is where I think some sort of resistor was. I'm of the agreement that usually they burn out for a reason.

Do you know if it's possible to get the whole board?

 

I had never heard of an XDT 40 drilling machine. I assumed it was some sort of CNC coordinate drilling machine until I googled it. I think you would have to contact the manufacturer to obtain a replacement board.

It resembles the older A-M-C BLDC servo drives I have used in CNC applications, they could be ran open loop with just a 0-10v analogue signal.
IOW a 10k pot set up.
If you can find one for that size motor, they often comes up on Ebay etc

 

You guy are awesome. I appreciate the replies. I think I found a guy in my area that can figure this out thanks to you guys helping me be able to explain it better.
