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 […]

How to calculate required input power for a gearmotor
The first place to start when sizing a gearmotor is to determine the required output torque and speed. But once torque and speed are defined, you’ll also want to know the required input power for the motor — particularly if the gearmotor uses an AC induction motor, where the power rating (typically given in horsepower) […]
How to size an electric-motor-driven chain-and-sprocket system
In previous motion-sizing articles, we reviewed how to properly specify (using software) a ballscrew-driven motion axis. Then we reviewed how engineering teams can use a similar software-based approach for sizing rack-and-pinion-based servomotor-driven axes on the same five-axis gantry. Now we’ll explore the process for sizing the components (using that same software) for an electric-motor-powered axis […]
What does motor insulation class specify and why is it important?
Any time current flows through a wire — such as the windings in a motor — resistance in the wire, as well as other losses, cause heat to be generated. This heat will eventually transfer to other parts of the motor, causing them to degrade over time. One of the key components affected by this […]

NASA’s Perseverance rover heading to Mars with maxon drives aboard
This month, NASA will be sending its fifth rover to Mars. Its main mission is to collect soil samples that will be analyzed on Earth at a later time. The rover will also carry a helicopter that will perform the first flights on the Red Planet. maxon’s precision dc and brushless dc motors will be […]
WITTENSTEIN releases new NPL-W corrosion-resistant gearbox
WITTENSTEIN alpha, a provider of high-precision servo gearboxes and drive systems, has launched a new corrosion resistant gearbox to support the increasing market demand for components that can withstand processing, overspray and cleaning environments.

Trends in gears and gearmotors for eMobility • washdown • customization
The fundamental mode of operation for gearing and its transmission of mechanical power remains unchanged — as has that for the electric motors with which they pair. But innovative variations have become increasingly common and include more custom gearing, compact designs, and better gearboxes and servogear sets (including helical gearing) for efficiency. Gearing and gearmotors […]
