Overview
The Kpower M0900 is an analog servo motor for robot joints, R/C models, industrial equipment and educational robot kits. Its model-specific specifications list 10.5 kg·cm torque and a speed of 0.13 s/60°, with no test voltage stated for either value. A splined output shaft, three-wire lead and four mounting holes support mechanical integration, while metal gears and a DC brushed motor provide the drive mechanism.
Features
- Analog servo classified as a high-torque model.
- Splined output shaft with a central threaded hole; horn spline specified as 25T, Ø5.7 mm.
- Mounting ears with four mounting holes.
- Three-wire lead for electrical connection.
- Metal gears, a DC brushed motor and potentiometer position sensing.
- Plastic case with two ball bearings (2BB).
- 120° travel angle, listed as customizable.

Applications
- Robot-joint actuation: Connect joint linkages to the splined output shaft and secure the servo through its four mounting holes.
- R/C model mechanisms: Drive model linkages with the specified 120° travel and 0.13 s/60° no-load speed.
- Educational robot kits: Build servo-driven joint and linkage demonstrations using the mounting ears and potentiometer-based position sensing.
- Industrial-equipment mechanisms: Integrate rotary linkage actuation using the metal gear train, observing the 4.8–8.4 V operating range and −10 to 50 °C temperature range.
