Overview

The Kpower M0300 is an analog servo motor for R/C models, robot joints, educational robot kits and equipment actuation. Its 40.7 × 19.8 × 37.7 mm body weighs 58 g and combines precision-machined metal gears with potentiometer position sensing. Operating at 4.8–8.4 V, it lists PWM, TTL and RS-485 protocols, a customizable 120° travel range and a no-load speed of 0.12 s/60°.

Features

Analog servo design with a DC brushed motor.
Precision-machined metal gears and high-speed response; M0300 is designated as a high-speed model.
Long-lifespan potentiometer for position sensing.
Plastic case with two ball bearings (2BB).
Mounting ears with four mounting openings.
25T output horn spline with a 5.7 mm diameter.
120° travel angle, customizable.
