Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications—such as robots and processing and packaging machinery—and consumer ...
A previous article (Standard Step-Motor Driver Interface Limits Performance) on step-motors berated open-loop stepping and the desperate methods used to avoid missed steps and acceleration limitations ...
The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...
