The FSMA evolution is ongoing and Kollmorgen continues to enable innovators to meet the requirements of making food production and packaging safer.  Kollmorgen’s White Paper “Food Safety Regulatory Requirements”  explains the background of FSMA as well as the implications on machine design.  We recognize that not all facilities have the ability to build a completely new plant from the ground up.
Collaborative robots are designed to work safely with and next to their human counterparts.  A subset of collaborative robotics has innovative safety techniques that completely eliminate the need for a safety barrier between the human and the robot.  This enables a wide range of applications to deploy and benefit from this collaborative robot technology.

Question: I need to operate a servo motor in a vacuum, what are some considerations? 

Answer: In a word?  Outgassing.  You might think that proper motor sizing is a big issue, it always is, however if you can't conform to the other process requirements, there is no point to attempting to size the motor.  The biggest issue for any given motor selection to be run in a given vacuum for a specific process is the outgassing requirement, or rather, the avoidance of materials that would affect the process being performed and/or the life of the motor.

There is a lot of discussion about the 1.8 degree step angle versus 0.9 degree step angle of industrial hybrid stepper motors.  Most stepper motors today have the standard step angle of 1.8 degrees, resulting in a 200 step per revolution.   However, in the early days of stepper motors, before microstepping, low end resonance played a significant role in many applications.

As it turns out, "going small" is an effort that traces back to the first steppers ever manufactured. Released in 1952, the Sigma "Cyclonome 9" series, one of the first steppers ever designed, was the first standard offering of its kind. Motors had a frame size of 1 3/16 inches, roughly the size of a modern day NEMA 11 motor. With a torque range of 1 - 12 oz-in, common applications at the time included printers, tape readers, and chart drive and display controls. Just like today, the small form factor of these motors allowed OEMs to reduce the overall size and footprint of their machines.

I often see some confusion in various customers’ minds regarding encoder performance with automation systems which have servo drives or variable frequency drives (VFD). Some customers feel that when they are providing best in class encoders, the system must be highly accurate.

Sounds logical? … Yes, but there are some other points to consider also.

So everyone’s heard the phrase “think outside the box.”

And at Kollmorgen we do that. But the reality is we have to think about inside the box. It’s our job to protect inside the box. Our OEMs need us to be ever conscious of inside the box so that the box works and is dependable. But OEMs also look outside the box - does it fit, is it smaller, what’s the advantage?

What should you consider when factoring IP Rating into your specification and what other environmental factors should be considered when specifying motion products?

As a manufacturer of motion control products for a variety of markets, Kollmorgen Application and Sales engineers get involved in specifying products into all kinds of environments. Often these environments can be wet and thus an IP (International Protection) rating needs to be considered as a part of the specification of our product.

Unlike fieldbus communications only being supported by particular models of the AKD servo drive, Modbus TCP communication is supported by all of the AKD models. Whether you have a simple "analog" drive, an indexing drive, or an AKD with BASIC programming, you have the capability of using Modbus communication. It is a simple, easy to use, standard communication protocol that can be used in a PC, PLC, or HMI to talk to any AKD drive.

A key driver for the current trends towards increasing use of electric motors in oil and gas applications is the ability of electrically driven systems to substantially improve system reliability, reduce downtime, and the limit the possibility of a leaked fluid discharge into the environment. Designers of oil and gas equipment are looking for the smallest, lightest, simplest solution with the least impact on the environment. While the best solution will be different for every application, it’s clear that the trend in the industry is favoring electric motors.
