Motor and Gearbox Pairing

July 21, 2016

Originally, gears and the structure that houses them (called gearheads, gear reducers or gearboxes) were created for two main reasons: To increase motor torque To enable more adjustments to be made to a motor’s speed. However, advancements in technology has enabled gearboxes to make additional progress in permissible inertia and vibration reduction. These changes are […]

Planetary Gear Reducers: Rotating Around the Sun

October 15, 2013

Planetary gear reducers belong to the epicyclic family of reducers, since the planet gears trace epicycloidal curves in space—very similar to how the popular kid’s toy, the spirograph, works[i]. Simple planetary gears are arranged with a centrally located, externally toothed sun gear that meshes with one or more externally toothed planet gears. As the name […]

How to use the Motor Search Tool

Narrow your search by selecting motor type, gearbox, voltage, and phase options for your desired motor.

Select a dominant variable: choose one of the three parameters to narrow your search. The selected variable determines which slider bar you will be able to manually move.

Use the slider corresponding to your dominant variable to further narrow your motor selection. The other sliders will automatically move to show available ranges based on the range of your selected variable.

Results will upload as your search criteria changes. If you have any questions regarding your results or how to use the search tool, you can chat with us using the green tab on the left-hand side of your screen.
