Bought a brushless servo motor, now what?

Hi,

I guess I have done a stupid thing, but I hope someone can help me out.

I wanted to put a brushless motor on my home built mill and found this great deal on this motor on ebay.... Seemed like a good idea at the time.

It was advertised as an brushless DC servo motor. It has a specifications plate (picture attached)

What literature I can find from Kobold in germany, it is a three phase synchronous servo motor. Its a Kobold KSY 464.80 servo motor. Not the current model "D" KSY, but the older one.

Seems like a strong motor, 8000 rpm, 210 volts, 13 amps. So now, I am looking for a servo motor driver to get to power it. And I am lost. I don't know what to get to power it, and I don't want to overspend.

I really don't need all that power, so if I want to run it at 1/2 to 3/4 hp, and buy a lower voltage/amperage driver, can I? I know it will limit RPM, but I can deal with that with pulley size setup. I'm doing light duty small diameter mills anyway.

Ideally, I would like to get a 115 ac line powered all-in-one driver that would allow analog speed control as well as future position/step/direction control.

Perhaps a Axiom DV10 (If I could get one cheap) or one of the A-M-C BE25A20AC devices. Would either of these do what I want?

Thanks in advance for any thing you can share.
I'm thinking I got in over my head. Maybe someone here can help me out?

The first thing to establish is what kind of commutation does it have, and if it includes an encoder
I believe the lower torque values are the operating values, the higher ones are the max before demagnetization.
Is it a BLDC or a AC sinusoidal with maybe resolver feedback?
Al.

The Kobold data sheet I have says these are "three phase synchronous". The usual configuration says resolver, but this motor seems to have a different suffix, IE, the "R6", than the usual R4 suffix. From what I can glean, this seems to be an encoder option. I hope. I won't know for sure until I get it later in the week.

Anyway, if it's a resolver, I guess I'm SOL. I was hoping to use it to drive a spindle with speed control.

If you can establish the pole count, you may be able to fit one of the encoders that Renco are dumping on Ebay right now for $20.00, and make it a BLDC.
Then you could use a AMC drive.

The manual says this is a 6 pole motor. The "464" means size 4, 6 pole.

So the Renco encoder or who's-ever if you should fit one, should be a /3 for 3 pole pair.
