Recommend a Servo ?

[murphy625]

I need some recommendations.

I currently am working with Control Techniques Digitax drives and DutyMax DS servo motors that have resolvers on them.. These motors can not be used with any other drive because of the darn resolvers.

I did not know about resolvers when I purchased these units as a set.. I actually have 3 drives and 3 motors to match... 1.3KW is the one I am using. The other is way to big as its made for a 7.5KW motor and is allot more than I need.

Anyhow.. I am having problems.. I think the drives might be bad and I want to replace them with normal "off the shelf" type servo motors and drives. (if there is such a thing).

I am looking for a ~1.3KW motor with a normal dual quadature encoder and a drive to match it or that can be used with it. I need 480volts!! ouch right? Im not to worried.. If I found the right combination, I might go with a 3phase 220 setup.

Can someone recommend some drive motor combo's? How much trouble is it to use one manufacturers motor with anothers drive?

What about allen bradley? I see these everywhere and I am wondering if there is anything special about them.. I've heard that fanuc is near impossible to get to work with non-fanuc equipment.

Suggestions? I dont have thousands to spend so I have to find stuff used.

Thanks!

Anyone????

With AC & DC brushless drives it can sometimes be a pain to mix & match, definately not as easy as DC. I would look for a combo Kollmorgen, Aerotech, ElectroCraft, Parker as some.
480 volts is going to be a real limiting factor.

Al,
If I went the DC route, what would you recommend.

DC servo motors aren't really made anymore. They don't last long compared to brushless, and are more expensive to manufacture. As for the servo drives. I think I would try worldservo, simpleservo, or AMC. The drives will be around $500-$1000 each for the cheap ones. The servos will cost a fortune unless you find some surplus. The problem with ebay is that you will hardly ever find more than 1 of the servo you want. Let us know how it turns out.
