help with motor controller

[gungatim]

I think this qualifies as a tool...

picked this up at an auction for $5. not sure what I can do with it.
any ideas?

anyone know how to wire it up?

Looked up the model and couldn't find anything at all, maybe it was homemade...

can I use it on any DC motor?

appreciate any help anyone can give.

Thanks!
Tim.

Looks vaguely military, or military related. Without a wiring diagram its not going to be very useful. The use of 6 pin connectors for the motor connections is interesting, and suggests something other than regular old DC motors.

I'd have bought it for $5 too, but mainly just to strip parts for other projects.

the canon plugs definitely make it look Military

Might be a DC supply for some servo motors. Did you look inside yet?

not yet. i'll probably take it apart and see what it looks like inside tonight.

can't believe there is nothing out there on this thing, maybe there is a mfgr. name or something inside that will help...

Don't kill me if I'm wrong. But I "think" that's a DC brushless controller with a pulse width modulation circuit board. Very efficient, but might not work with a regular motor.

The CW/CCW switches are pretty cool! Nice toy for 5 bucks!

Looks shop-made. That case would be sub-standard for typical mil use. The connectors are very common all over industry.

With a 3A fuse feeding BOTH motors, this is surely for very light-duty use.

good catch. I'm studying now for my ham license test tomorrow morning, and I learned V=CR and P=VC (VCR/PVC easy to remember). so 120v = 3 x 40...-losses/2 moters would be around <20 amps ea, so maybe 2hp? but if it's dc there'll be a decent sized rectifier in there, it looks too old to have any sort of PWM logic board. in fact, the pic of the back shows what looks like a power supply that slides in, maybe even tubes?

I'll post what I find inside when I tear into it...doubt it's military too. way too shoddy work, and no s/n or anything...

Thanks all for your info!!

Not shoddy like I thought, very well made. And it works based on my limited testing

So what kind of motor can I use it on? Lathe? Drill press?

 

[larry_g]

Watts = amps X volts
760 watts = 1 hp

3a X 120v = 360 watts

360/760 = .47 hp

So less that 1/2 hp combined for the two motors.

The Slo Syn controller says to me that is a stepper motor controller.

Is your unit something like the TBM105. Look at the schematic posted there. Way back when I started in the manufacturing plant these small Slo-Syn motors and controllers were use to feed stock into different machines, think small electronic pieces. Not a lot of hp required but speed control and holding power were required. So the idea of using this as a motor controller in a tool as your thinking is not purpose of the box.

I was going to guess stepper motors, but you got there before me. This is from 1970s or 1980s I would guess.

The resistors are to limit motor current. Running the steppers over voltage and limiting the current gives snappier response. Efficiency is best described as "poor".

Slo Syn steppers are still out there, or at least in my cellar. You may be able to find a wiring diagram in old catalogs from Electro Sales. Good luck.

maybe I can use it as a heavy duty power supply for my radios then. i'll have to see if I can get it regulated down to 12v. otherwise I guess it gets stripped for parts and e-scrap.
