The Kpower DHV823 is a coreless digital R/C servo motor for radio-controlled vehicle steering and positioning mechanisms in robotics and automation. Its 4.8–8.4 V operating range and 330 Hz PWM control help buyers match power and control requirements. With an aluminum-alloy housing, metal gears and dual ball bearings, it delivers a specified no-load speed of 0.08 s/60° at 7.4 V in a 40 × 20 × 39 mm package.
Features
Energy-efficient coreless motor for responsive positioning.
CNC-machined full aluminum-alloy housing.
Precision-machined, impact-resistant metal gears and dual ball bearings (2BB).
Potentiometer position sensing.
Digital PWM control, including an advertised 330 Hz operating frequency.
25T output spline with a 5.9 mm diameter.
Wire length, control type and position sensor customization are subject to supplier confirmation; request details before specifying a custom unit.

Applications
RC road and off-road vehicle steering: the coreless motor and 0.08 s/60° no-load speed at 7.4 V support responsive steering-linkage positioning.
Service robots and industrial robots: use the potentiometer feedback and metal-geared output for controlled positioning of small mechanisms.
Industrial inspection robots and robot dogs: the 72 g weight and compact housing help with actuator placement in space-constrained positioning assemblies.
Industrial automatic testing equipment: use the servo to position fixtures or operate small test mechanisms with defined pulse commands.
Agricultural spraying machines, agricultural spraying drones and other UAV drones: use the compact servo for positioning control linkages or adjustable mechanisms.
Medical endoscope mechanisms: the compact housing and position sensor support mechanically controlled positioning tasks.
