Gearmotors use gears to reduce speed, which makes more torque available. The kind of gears used in gearmotors have an impact on the available torque, but also on things like noise levels and accuracy. In fact, one of the more common sources of inaccuracy in gearmotors is due to gear backlash. So reducing the amount […]

New mini planetary gearmotors for small stepper motors
Applied Motion Products’ new PH Series mini planetary gearmotors are used with small step motors in NEMA 8, 11, and 14 frame sizes. The small design of the gearheads allows them to be paired with small motors and doesn’t adversely affect the outside dimensions of the combined gearmotor. These gearmotors are used in applications where […]

Bison’s line of right angle gearmotors provides the power and reliability to meet customers’ needs. PMDC […]
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 […]
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 […]
