Industrial White Papers

Comparing Open Loop and Closed Loop Stepper Systems

Innovative StepSERVO™ closed-loop stepper technology

Posted on April 3, 2017 - ( views)

by Elisa Campo

Applied Motion Products Inc., represented by Mclennan, has released a new white paper on its innovative StepSERVO™ closed-loop stepper technology that is available in a wide range of competitively priced integrated motors that combine NEMA 11, 17, 23 and 24 sized microstepping motors and drives with a feedback encoders and motion controllers and optional fieldbus communications. The 12-page resource compares the technology with open loop stepper systems and demonstrates its capability for higher acceleration, faster machine cycles and greater productivity as well improved energy efficiency and quieter operation.

The white paper, authored by Jeff Kordik, AMP’s CTO, principally poses the question - ‘What if…you could make a step motor faster? And quieter? While saving energy?’; and goes on to explore the benefits of StepSERVO by way of fully tested comparative torque curves, move profile and throughput rate graphs as well as motor heating, power consumption and positional accuracy illustrations. Also covered are noise level reduction as well as the all-important cost comparison between AMP’s technology and traditional open loop steppers. The comparison concludes that the StepSERVO is slightly more expensive, mainly due to the addition of the high resolution 20,000 count/rev encoder but this is more than made up by the benefits of higher performance and more efficient operation.
