Planetary gearsets offer applications advantages over other gearsets, including multiple kinematic combinations, power density, big reductions from compact setups, and pure torsional reactions. Planetary gearboxes also boost overall design efficiency. Losses never exceed 3% per stage, so the sets transmit most energy for productive motion output. In applications driven by servo systems, gearboxes also reduce […]

How custom BLDC motors boost performance and lower costs
From packaging to communications, BLDC servomotors are gaining market share in a variety of industries — and for good reason. They deliver high torque and smooth rotation (with minimal torque ripple) and lend themselves well to cost-saving customization. By Ralph Adams • President | Orbex Group Design engineers typically rely on off-the-shelf brushless dc (BLDC) […]
What are linear springs and how do they work?
Springs that follow Hooke’s Law are often referred to as “linear springs” because they have a linear relationship between load and deflection. A linear spring has the same diameter along its entire length, and this uniform diameter gives it a constant spring rate. In other words, the spring rate doesn’t change regardless of the load acting on […]
