Overview

The Kpower DHV816 is a coreless servo motor for RC cars and aircraft, robotics, and compact positioning tasks. Its 34 × 15 × 28 mm body combines a 7075 aluminum case with copper and aluminum-alloy gears. Operating from 4.8–7.4 V, it provides 120° ± 3° travel, with voltage-specific speed and stall-torque figures to help match the servo to the mechanism and power supply.

Features

Coreless motor with a CNC-machined aluminum case.
7075 aluminum housing and copper plus aluminum-alloy gears.
Finned center housing, splined output shaft and slotted mounting tabs.
900–2100 μs control-signal range, 3 μs dead band and 50–333 Hz refresh frequency.
30 g ± 1 g weight and 28 AWG PVC wiring.

Applications

RC cars and aircraft: Operate steering or control linkages with 120° ± 3° travel in a compact 34 × 15 × 28 mm body.
Robotic mechanisms: Position compact joints and linkages using the splined output shaft and slotted mounting tabs.
Smart-home mechanisms: Actuate small positioning linkages where the compact housing and 4.8–7.4 V supply range suit the design.
Medical-device mechanisms: Provide compact positioning motion within the stated travel, voltage and temperature limits.
