Overview

The Kpower DHV826 is a digital metal-gear servo motor for remote-control airplanes, drones, gliders and robotic arms. Its coreless motor, steel gears and 40 × 20 × 39 mm housing provide a compact actuator for controlled angular movement. A 120° ± 3° travel angle and voltage-specific torque and speed figures help buyers assess movement requirements, while PWM, TTL and RS-485 are listed control interfaces.

Features

  • Digital servo with a coreless motor and high-precision steel gears.
  • CNC-machined 7075 aluminum case.
  • High-torque model classification, with performance values detailed by operating voltage below.
  • Listed control interfaces: PWM, TTL and RS-485.
  • Signal range of 900–2100 μs, 3 μs dead band and 50–333 Hz refresh frequency.

Applications

  • RC airplane and glider control linkages: use the servo's controlled angular travel to move aircraft control mechanisms, with the published dimensions supporting installation planning.
  • Drone mechanism actuation: drive an angular linkage using the digital servo and metal gear train, with voltage-specific speed and current figures available for system sizing.
  • Robotic-arm joint or linkage movement: use the 120° ± 3° travel for bounded angular motion, selecting loads with reference to the voltage-specific stall torque ratings.
