Overview

The Kpower DMM0900 is a standard analog servo motor for RC models, mechanical arms, robots and DIY motion-control projects. Operating at 4.8–6.0 V, it combines metal gearing, a CNC aluminum middle case and dual ball bearings. Its 25T metal output shaft supports linkage attachment, while the JR/Futaba-compatible connector provides the control connection. Travel is specified at 120° ± 3°.

Features

Metal drivetrain: copper and aluminum gearing with a 25T metal output shaft, external splines and a central threaded hole.
Aluminum construction: CNC-machined 7075 aluminum middle case for heat dissipation.
Bearing support: dual ball bearings.
Gear treatment: imported gears with anodizing treatment.
Control features: anti-burn and anti-shake features.
Mounting: mounting ears at both ends, with two mounting slots per end.
Connection: permanently attached three-wire lead terminating in a black, three-position JR/Futaba-compatible connector.

Applications

RC cars and model boats: actuate steering or rudder linkages using the 25T output shaft and specified 120° ± 3° travel.
Model aircraft and drones: position mechanical control linkages using the attached servo lead and JR/Futaba-compatible connector.
Mechanical arms and robots: drive positioning linkages with metal gearing and dual ball-bearing support. Stall torque is 13.0 ± 0.20 kg·cm at 4.8 V or 16.5 ± 0.20 kg·cm at 6.0 V.
DIY and smart-home projects: add controlled movement to small mechanisms using the 900–2100 μs signal range and 4.8–6.0 V supply.
