[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

Maxon Precision Motor's newly released DC servo motor controller, the ESCON 50/5 OEM module. This mini OEM plug in module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that can ...

Brushless DC motors, and their associated drive electronics, tend to be expensive and complicated. [Ottoragam] was looking for a cheaper alternative and built this Brushed DC motor servo controller ...

In an increasingly virtual world, the ability to simulate touch provides powerful advantages, such as potentially allowing an online shopper to, “feel” a shirt fabric. Enter the discipline of haptics, ...

A motor-drive servo amplifier's output voltage has a fundamental frequency and amplitude that corresponds to the motor speed, torque, and number of motor poles. PWM amplifiers, by their nature, also ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

By co-designing the drive system with the pipetting channel, manufacturers can ensure compact, efficient, and high-precision ...
