Learn how to calculate the gear ratio of a gear reduction motor using the tooth-count formula, input and output speed, torque effects, and multi-stage ratios.

Learn how a gear reducer motor converts electrical input into lower-speed, higher-torque output through its motor, gears, bearings, and shaft.

Learn how to select a small gear reducer motor by speed, torque, ratio, duty cycle, mounting, power supply, and application conditions.

Compare parallel-shaft, inline, right-angle, fixed-speed, reversible, brake, and speed-controlled small reducer electric motor types.

Choose Small AC Gear Reducer Motors by speed, torque, power, ratio, voltage, duty cycle, shaft layout, and application requirements.

To select gear motors correctly, start at the driven load: define the required output speed, continuous and peak torque, duty cycle, power supply, mounting, shaft loads, and operating environment.
