• We are excited to introduce the launch of a brand new product selection tool – Kollmorgen Stepper Optimizer. Optimizer provides multiple ways for you to discover what Kollmorgen stepper motor works best in your application. Comprised in the tool are Kollmorgen’s most highly recommended stepper series. This includes our newest stepper product, the PMX Series, as well as our  popular Powermax and POWERPAC product families.

  • 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.

  • There are a number of situations that call for crossing over and replacing an existing motor with a newer servo. These can include: product obsolescence, cost savings, lead time issues, or upgrading to newer technology. The specifics of each application could lead to an endless number of important factors to consider. In this post I will try to (briefly) identify those that are most common and their correct order of concern.
