Product overview
The Kpower HBL838-W 30kg Fully Waterproof Brushless Servo is a servo component for applications including drones, fixed-wing drones, underwater robots, commercial cleaning robots and desktop robotic arms. Its construction combines an aluminum alloy case, metal gears and a brushless motor, with bearings specified as 2BB. A potentiometer provides position sensing. The unit measures 40x20x38mm and weighs 66g (2.33oz). Its mechanical output has a 25T spline with a diameter of 6mm.
The servo operates across a 9-13V supply range and uses PWM signaling. Travel is 180°, with customization supported for travel angle and signal and protocol. Waterproofing is rated IP67, also with customization supported, and the operating temperature range is -10 to 50°C. Torque is specified at stall as 30kg·cm, while stall current is 2500mA. The speed rating of 0.04sec/60° applies under no-load conditions; the torque and speed figures therefore describe different operating conditions.
