The primary transmission structures are: planet gears, sun gears, and outer ring gears.

The TBT servo motor reducer features a single-stage reduction ratio of: 06, 10, 15, 20, 30, 40, 50, 60.

Servo motor reducers offer high rigidity, precision, high transmission efficiency, high torque-to-volume ratio, and maintenance-free features, distinguishing them from other reducers.

Due to these features, servo motor reducers are commonly installed on stepper motors, servo motors, or brushless motors to reduce speed, increase torque, and match inertia.

Servo motor reducers can achieve an rated input speed of up to 18,000 rpm (which varies with the reducer's size; larger reducers have lower rated input speeds). Industrial-grade servo motor reducers typically have an output torque not exceeding 2,000 Nm, while custom-built high-torque servo motor reducers can reach over 10,000 Nm. Operating temperatures usually range from -25℃ to around 100℃, and can be adjusted by changing the lubricant.
