Product overview
The Kpower DHV813 is an ultra-thin flat servo for fixed-wing drones and RC model aircraft, with applications also including industrial automation, smart cat beds and medical equipment. Its architecture combines an aluminum-alloy housing, a coreless motor, metal gearing and potentiometer position sensing. The body measures 30x10x35mm, is 10mm thick and weighs 29g (1.02oz). Mechanical connection is through a 25T Φ4.93mm output spline. The bearing specification is 2BB, with impact-resistant ball bearings supporting the output shaft.
The specified configuration uses PWM control and provides 180° travel across a 4.8-8.4V supply range. At 7.4V, stall torque is 9kg·cm, no-load speed is 0.09sec/60°, and stall current is 2500mA. Static current is 6mA. Machined steel gear teeth provide less than 0.5° backlash, alongside a 3μs dead zone and millisecond-level dynamic response. Operating limits are -10 to 50°C, with IP42 ingress protection. Customization is supported for travel angle, signal and protocol, and ingress protection.
