Overview
The Kpower DHV825 is a digital coreless servo motor for remote-control airplanes, gliders, drones and robotic arms. It combines high-precision steel gears with a 7075 aluminum case and lists PWM, TTL and RS485 control interfaces. Its 120° ± 3° travel and voltage-specific speed and stall-torque specifications help buyers assess motion requirements, while the 40 × 20 × 39 mm dimensions support installation planning.
Features
- Digital high-voltage servo with a coreless motor.
- High-precision metal gears, specified as steel.
- 7075 aluminum case.
- PWM, TTL and RS485 control interfaces.
- 3 μs dead band and 50–333 Hz refresh frequency.

Applications
- RC airplane and glider control: Position control linkages through 120° ± 3° of travel, using the voltage-specific no-load speed figures to assess movement timing.
- Drone mechanism actuation: Provide controlled angular movement for onboard mechanisms where the servo's dimensions, travel and control interface meet the installation requirements.
- Robotic-arm linkage positioning: Use the specified travel, 3 μs dead band and voltage-specific stall-torque figures to assess a linkage's positioning and load requirements.
