Overview

The Kpower P0090 is a 9 g plastic gear micro servo for RC aircraft, UAVs and compact robotic mechanisms. Its 22.7 × 12.5 × 26.9 mm body supports space-conscious installations, while a 275 mm lead provides connection reach. Torque is specified at 1.6 kg·cm at 4.8 V and 1.8 kg·cm at 6.0 V, with corresponding speeds of 0.10 and 0.09 s/60°.

Features

POM plastic gears and a translucent blue plastic housing with mounting tabs.
Coreless DC brushed motor with potentiometer position sensing.
Two ball bearings (2BB).
120° travel angle, with customizable travel specified.
21T output horn spline with a 4.8 mm diameter.

Applications

RC aircraft and fixed-wing UAV mechanisms: compact servo actuation for control linkages where the 9 g weight and small body help limit installation mass and space.
Micro robots and multi-legged bionic robots: joint and linkage actuation using a compact servo with 120° travel.
Smart finger robots: small finger-linkage mechanisms that benefit from the compact housing and 275 mm lead.
STEAM education and robot toys: moving joints and demonstration mechanisms using a lightweight plastic gear servo.
Intelligent medical-device mechanisms: compact mechanical actuation where a small, lightweight servo is required.
