The UDMSD series of EtherCAT drive modules from ACS Motion Control offers two or four axes of control for small servo, step, and voice-coil motors. Small size, low weight, and minimal cable interface ...

[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 ...

From single-cable systems to energy-harvesting encoders, new feedback device features improve accuracy, reduce downtime and ...

Designed as a replacement for two circular connectors, new Cm3 2x power connectors provide maximum power in a minimum size package featuring 50% less weight than conventional circular connectors. The ...

There is a whole lot to know about servo motors and drivers. You could make a career out of specializing on that one topic. This article is a very small collection of some of the features to consider ...

Figure 2: By using smaller servo drives, robots have less dead weight to deal with, reducing their wear-and-tear. The ongoing trend of micro-sized servo drive technology is driven by Moore’s Law and ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...
