Product overview
The Kpower DMC808 is a compact, lightweight micro servo. Its listed uses are fixed-wing drones, RC remote-control helicopters, inspection drones and medical equipment, and it is classed as an RC, robotic, smart-home and drone servo. It measures 23.2x12x23.8mm and weighs 26g (0.92oz). The CNC-machined aluminium alloy case is designed for high-efficiency heat dissipation. Inside, a high-speed coreless motor drives a metal gear train supported by two ball bearings (2BB). A potentiometer provides position feedback, and the output uses a 25T Φ4.9 spline. Kpower provides a specification sheet, a dimension drawing, a 3D model, a user guide and control software for integration work.
The servo runs across a 4.8-7.4V range, takes a PWM signal and also supports low-power operation at 3.7V. At 7.4V it delivers 3.6kg·cm of stall torque and a no-load speed of 0.06sec/60°, and its stall current at that voltage is 2200 mA. Built-in functions include programmable electronic protection, soft start/stop, and stall and overheat protection. The standard travel angle is 180°, the protection rating is IP42 and the signal protocol is PWM; customisation is supported for all three. The operating temperature range is -10 to 50°C.
