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 ...

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, ...

Closed-loop control of stepping motors integrates feedback from position or current observers to achieve high precision, rapid response and robustness against load disturbances. Unlike traditional ...

Not missing a beat: Here we take a look at why open-loop steppers lose steps, as well as some solutions to the problem. As in the below) half-stepping produces eight steps per electrical rotation — ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

Proper evaluation of torque margins across the full motion profile prevents stalling and ensures consistent performance under varying load and speed conditions. Mechanical resonance can cause ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

Increasingly elaborate Rube Goldberg schemes for controlling step-motors have developed over the years that try to pace stepping to avoid missteps. This direction of development is fundamentally ...
