Here's a copy. I used to work for Kollmorgen, I have lots of their documentation and a lot of their obsolete components in stock where I currently work, especially BDS4, BDS5 and Servostar CD drives....

The steel balls are going to wear the aluminum very quickly. As someone who worked in the linear bearing industry for a little while, there is so much black magic to linear bearings working well and...

A picture is worth a thousand words...

The first step is to find the feedback type. There are only a few drives out there that can handle a wide variety of feedback devices within a single part number. You'll be really sad if you buy a...

I work for a PacSci distributor. From the part number, this is a brushless DC motor that was custom for an OEM.

Since it doesn't have standard feedback (resolver), i wouldn't be surprised if it...

The Kollmorgen S300 drives can handle this sort of application. They use what's known as 'Wake n Shake' technology that pings the motors with short bursts of current, and then based on the movement,...

Hello,

I'm looking for a specific product, and I have a hunch it might be out there already.

Specifically, I want to have a generic project box that has roughly 8 toggle buttons or switches and...

I can ensure you that the ratio is simply too high to use with steppers and get any sort of reasonable performance from steppers unless you're planning on getting something less than 50 RPM out of of...

Others might disagree, but I say, "Caution, Caution!'

What you're talking about makes sense on the surface, "I'll just drive two leadscrews at the same time from two motors at the same speed. No...

If you're looking for full industrial enclosures, say greater than 12" x 12" x 12", Saginaw Controls is the undisputed leader in enclosures. Lower cost competitors like Automation Direct also sell...

I have a few thoughts on this. Hopefully what you're looking for is honest feedback.

Overall accuracy is different than repeatability, and both of these have as much to do with your transmission...

I agree with Al compeltly.

I'd also comment that for $1,250 - $1,400 you can get yourself a more modern and more powerful motor than something like that you've linked to. You can specify the...

David,

I agree with H.O. Higher speeds often require higher voltages. You've discovered what many people on these forums figure out the hard way: It's not about holding torque, it's about...

How fast do you want to spin, and what is the pitch of the screw?

The 25mm diameter screw with 10mm lead recommended above is rated for 362 inches per minute. Is that enough?

1" diameter with...

Even the cheapest imports that meet the speed specs you're looking for aren't that in the low hundreds. Even descent encoders at 2000/lines (8000 counts) per rev can run $60-$150

Why do you need...

Dave,

As someone that has worked in industrial environments for a few years now, I can't emphasize more that you get what you pay for when it comes to motors and cables.

While it's easy to buy...

Watch out for whip speed.

With a smaller pitch screw you'll be spinning the screw much faster to get the same travel speed, and may approach the screw's whip speed.

How long are you thinking...

Disclaimer: I represent Nexen Products in Illinois as a distributor.

With that said, the Nexen Roller Pinion System is awesome!

It has some pretty incredible properties compared to a typical...

Kollmorgen S300 drives.

They accept quadrature input, analog +/- 10 VDC, step and direction. Also can operate over SERCOS, Profibus, CANOpen, Ethercat field bus protocols.

3,6, 10 Amps...

I've visited the folks up at Centroid. I believe that they use brushless AC motors with incremental quadrature feedback. I know that most of their drives operated best with 240 VAC.

Kollmorgen...

Absolutely. I can provide screws that are machined right at the factory.

All I need is a drawing.

Dave,

Are the motors brush DC motors, or brushless motors?

If they're brush, you'll be fine. If they're brushless, you'll need to use a brushless servo drive.

You will need a power supply to...

Neil,

Are you sure that you need .001 accuracy, or do you need .001 repeatable? The difference might be upwards of $750 or more per axis, because you'll need ground screws instead of rolled.
...

I would group them as:

Stepper
Brush Servo
Brushless Servo
Induction Motors

A stepper drive applies DC voltage to alternating phases in the stator of the motor, stepping it along. If you...

+ Sealing of connectors and shaft (against fluid)
+ Flexibility in customizing the output shaft and mounting face to the application.
+ Warranty

I have a few thoughts. Since I haven't see the drives themselves, I don't have enough information to fully answer your question, so I'll respond with more questions.

Does the drive have an enable...

IPM = Inches per minute

How fast do you expect the CNC to move during machining?

You need to buy it from Rockwell Automation. I think it's $75.00.

Matt

Not sure if I understand what you're asking yet... are you saying you're not able to connect at all?



A quick back to basics thing to check is that you're using the right serial cable....

Dave,

I work for a supplier of industrial brushless servo motors. What is your price range, torque requirements, etc? What sort of drive are you looking to use?

Allen Bradley is definitely not...
