Overview
The Kpower DHV090 is a metal-gear, coreless digital servo motor for RC models, robots and desktop robot arms. It delivers 9.2 kg·cm torque at 6.0 V and 10.8 kg·cm at 7.4 V, with corresponding no-load speeds of 0.07 and 0.06 s/60°. Its 40 × 20 × 39.4 mm body and 63 g weight provide defined mounting and mass requirements for compact motion-control projects.
Features
- Coreless motor with digital servo control; labelled HV DIGITAL.
- Metal gears and an aluminum-alloy-and-plastic case.
- Potentiometer position sensing and two ball bearings (2BB).
- High-speed model classification, with a specified no-load speed of 0.06 s/60° at 7.4 V.
- 25T horn spline with a 5.82 mm diameter.
- 120° travel angle, with customization indicated for the travel range.

Applications
- RC cars, including 1/5-scale remote-control cars: steering or linkage actuation using the metal gear train and voltage-dependent torque output.
- RC aircraft and UAV drones: control-linkage movement where the specified 63 g mass, mounting envelope and no-load speed suit the mechanism.
- Robots and desktop robot arms: joint or linkage positioning using potentiometer feedback and the specified 120° travel range.
- STEAM education: hands-on servo-positioning and linkage projects using a coreless digital actuator.
- Industrial automation and industrial valves: positioning compact mechanisms or valve linkages within the specified torque and travel limits.
- Smart bidets and medical-device mechanisms: compact linkage positioning using the defined mounting dimensions and travel range.
- Underwater robot systems: mechanism actuation within a dry, protected enclosure; the IP42 rating does not provide protection for submerged operation.
