In any system where a motor drives a load to achieve precise positioning, velocity, or torque, the ratio of the load inertia to the motor inertia plays a significant role in determining the motor’s ability to effectively and efficiently control the load, especially during acceleration and deceleration portions of the motion profile. In this context, the […]

Apex Dynamics USA now sells only high-precision 42-mm helical planetary gearhead in industry
Apex Dynamics USA now sells the only high-precision 42-mm helical planetary gearheads in the industry. The Apex Dynamics inline and right-angle helical gearheads include model AB/AF/ABR/AFR 42 (42-mm square) gearheads in an array of single-stage ratios — including 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, and 10:1. Standard double stages range from 15:1 to 200:1. […]
What’s the difference between a dashpot and a snubber?
Dashpots and snubbers are two types of pneumatic device used for controlling the movement of a load — typically for the purpose of controlled deceleration or motion damping. Although they can be used to control rotary motion, the more common uses for dashpots and snubbers in industrial applications involve the control of linear motion mechanisms, […]
Electromagnetic brakes provide more stopping power for servo motors using less space
The BXR-LE brake series from Miki Pulley is a power-off, engaged brake design. When the stator is energized, the brake is disengaged allowing free rotation. When no current is applied, compression springs halt the brake rotor thereby stopping the input shaft rotation. This is an ideal feature to prevent rotation during power failure events. The […]
New high torque planetary gearboxes from Nanotec
For applications that require high torque, Nanotec offers new planetary gearboxes in two sizes and many reductions: the GP42 gearbox is designed for all motors with NEMA 17-flange as well as the DF45 external rotor motors from Nanotec. The GP56 gearbox can be combined with all brushless dc and stepper motors in sizes NEMA 23 […]
Miniature piezo components for medical device manufacturing
PI Ceramic (a division of PI Physik Instrumente) introduces a new family of micro components, including mini transducers, suitable for the most precise applications, including medical imaging, nanopositioning, fiber alignment, and optics/photonics. One of the latest applications of miniature piezo tube transducers can be found in scanning fiber/scanning catheter endoscopes (SFE). These miniature endoscopes provide […]
