When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

Nanotec has introduced a driver for stepper and brush-less dc (BLDC) motors with sensor-less closed-loop and field-oriented control (FOC). Intended for steppers from NEMA 14 to NEMA 34 and BLDC motors ...

Based on the Motorola (now Freescale) heavily used but obsolete SAA1042 stepper-motor-driver IC, this Design Idea describes a CPLD (complex-programmable-logic-device)-based implementation of a stepper ...

The world is digital today, and most information is represented in numbers. However, human nature is more “analog” and information is better represented in the old-fashioned way, using pointer gauges ...

Different types of motors need different types of drivers. Requirements for a variety of applications. Selecting the right motor driver is crucial to achieving the required functionality and ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...

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.

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, ...
