This paper explores the benefits and limitations of the stepper servo control technique, also called closed loop stepper, and explains why it is attracting serious attention from machine designers.
by Performance Motion Devices, Inc. A new drive technique called stepper servo has some engineers believing they have found the holy grail of positioning motion control - the high performance of a servo motor with the low cost of a step motor. This paper explores the benefits and limitations of the stepper servo control technique, also called closed loop stepper, and explains why it is attracting serious attention from machine designers.
