Product overview
The Kpower DMC808 8G All-Aluminium Hollow Cup Micro Servo is a compact actuator for applications including fixed-wing drones, RC helicopters and inspection drones. Its architecture combines a coreless motor, metal gears, an aluminum-alloy CNC housing, two ball bearings and potentiometer position sensing. Integration dimensions are 23.2x12x23.8mm, with a 25T Φ4.9 output spline. Despite the 8G wording in its model name, the specified product weight is 26g (0.92oz), which is the relevant figure for installation mass planning.
The listed configuration uses PWM control and provides 180° travel, with customization supported for travel, signal/protocol and ingress protection. At 7.4V, stall torque is 3.6kg·cm, no-load speed is 0.06sec/60°, and stall current is 2200 mA. The specified voltage range is 4.8-7.4V; a separate feature also states support for 3.7V low-power operation. Programmable electronic protection, soft start/stop, and stall and overheat protection accompany an IP42 rating and an operating temperature range of -10 to 50°C.
