Overview
The Kpower HBL150 is an HV brushless digital servo for RC aircraft, desktop robot arms and other angular-positioning mechanisms. Metal gearing and an aluminum mid case support its mechanical construction. Its voltage-specific performance is 14.5 kg·cm and 0.13 s/60° at 6.0 V, or 16.6 kg·cm and 0.12 s/60° at 7.4 V, helping buyers match movement speed and torque to their supply voltage.
Features
- Brushless motor with high-precision metal gears; classified as a high-torque model in the HBL series.
- Aluminum mid case and two ball bearings.
- Potentiometer position sensing and a 25T, Ø6 mm horn spline.
- HBL-series service-life claim of up to one million cycles; operating and test conditions are not specified.

Applications
- RC aircraft and UAV mechanisms: drive angular linkages using the voltage-specific torque and speed values to size the mechanism.
- 1/5-scale RC cars and 600H RC helicopters: actuate control linkages with metal gearing and a 25T, Ø6 mm output spline.
- Desktop robot arms and STEAM projects: move articulated joints or demonstrate angular positioning with potentiometer feedback.
- Industrial automation: position small levers, linkages and other rotary mechanisms using the brushless servo drive.
- Smart-bidet and medical-device mechanism development: provide angular actuation for mechanical assemblies.
- Underwater-robot internal mechanisms: provide angular actuation inside an enclosure that keeps the servo dry; the IP42 rating does not establish suitability for immersion.
