Overview

The Kpower DHV828 is a coreless servo motor with metal gears and an aluminum-alloy case for RC cars, aircraft and powered mechanisms. It operates from 4.8–8.4 V and delivers 29.2 kg·cm stall torque at 7.4 V, with a no-load speed of 0.13 s/60°. Its 72 g weight, potentiometer position sensing and 120° travel support selection for steering, control linkages and robotic mechanisms.

Features

  • High-torque, HV coreless servo construction with metal gears.
  • Aluminum-alloy case and two ball bearings.
  • Potentiometer-based position sensing.
  • 25T output spline with a 5.9 mm diameter.
  • 120° travel angle, with customization indicated.
