Can anyone recommend a keling driver for my machine?

I'm posting this here and in the stepper/driver forum, so please don't shoot me!

Can anyone recommend keling drivers for the x and y axes of my cnc machine?

It's a 4x8 router table using IDC P33V motors geared at 2000 steps per inch. The motors are 1260 oz-in, 2A/4A for series/parallel. Here is the data sheet:

The power supply is 56V, but I could get something else if necesary.

Thanks!

TG,

You may get by with the KL-6050, for sure you want to wire the motor in bipolar parallel configuration.
The motor inductance in series is astronomical.

The power supply voltage is near the max rating of the drive.
I would call John at Keling just to make sure.

It would be the most economical solution,

Thanks, I was looking at that driver but I wasn't sure if it was appropriate.

Would there be any disadvantage between that and a gecko for my application? e.g. the gecko g210?

Also, keling doesn't have a phone number posted on kelinginc.net, is that the correct site?

TG,

Yes the website is www.kelinginc.net

Phone number 630-254-8655 ask for John.

The Gecko is more robust than the KL-6050.

I emailed John and he suggested that the KL-8060 running at 60-70V would be more appropriate, so I think I'll just order those.

Ok, I talked to Keling and Gecko and they both used the formula 32 x the square root of the motor inductance to arrive at a recommended supply voltage for the motor.

My motor is 25mH which works out to 160v. The guy at gecko told me it would better to get a smaller motor since I'll be running at 1/2 voltage and 1/2 speed, but I could try using it with 80V.

So the most appropriate driver would be 4Amp with as high a voltage as possible, up to 160V.
