In motion control systems, gears are used to change the torque and speed delivered by a motor to a driven component. Depending on how the gears are arranged, they can either increase the delivered torque and decrease the output speed (the most common arrangement in motion control applications) or decrease the delivered torque and increase […]
Gears + Gearing
What are multi-stage gearboxes and when are they used?
Gearboxes are commonly used in motion control applications to change the output speed and torque from a motor to a driven component. By using a smaller gear with fewer teeth (commonly referred to as a pinion) to drive a larger gear with a higher number of teeth, the torque delivered to the load is increased while […]
Gears and gearmotor trends — more customized designs
Gearing and mechanical power transmission, in its fundamentals, remains virtually unchanged. However, innovative variations are becoming increasingly common and include more custom gearing, compact designs, and better gearboxes and servo-gear sets. Manufacturers are offering designers more customized solutions via more in-house engineering resources, simplifying the design process. More custom solutions also means greater integration with […]
Miniature gearing and planetary gearing in haptic feedback
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) […]
Industrial gear adapter from NORD for mixing and agitating processes
MAXXDRIVE industrial gear units are a good choice for use in large mixers and NORD has continued innovating in this field with its new SAFOMI (Seal-less Adapter for Mixers) adapter. This adapter features a flange with an integrated oil expansion tank, increasing operational reliability and requiring less routine maintenance over the lifecycle of the gear […]
