Overview
Kpower DMC026 is a digital servo motor with a coreless motor design, aluminum mid case, titanium gears, and 2BB bearings. It is specified for 4.8–6 V operation, includes a 25T spline output, and is rated waterproof. The product media also describes it as a “semi-aluminum coreless high-voltage servo” and mentions “operating voltage up to 8.4V”; unless otherwise confirmed for a specific batch/version, use the stated operating voltage of 4.8–6 V.

Details
The DMC026 combines a coreless motor with an aluminum alloy housing and precision metal gearing for efficient, responsive control.
Designed for compact builds where low weight and coreless efficiency matter, from drones to high-end RC projects.
Control options include PWM, TTL, and RS485, with a metal gear train and CNC-machined aluminum housing for durability.
Multiple horn styles make it easier to match the output to your linkage geometry and mounting needs.
Standard servo pulse widths control position, and many digital servos can accept higher-frequency control signals.
Customization support is available for appearance, performance targets, wiring, and protocol requirements.
Wiring follows the common 3‑wire servo standard: GND, Vcc, and Signal.
