Product overview
The Kpower HBL838 28kg Brushless Full Aluminum Case Standard Servo is a digital actuator for high-torque, high-speed motion, with applications including fixed-wing drones, desktop robotic arms, industrial automation and service robots. Its architecture combines a brushless motor, precision-machined metal gears, potentiometer position sensing and a digital MCU drive system. An aluminum-alloy housing encloses the mechanism, while double ball bearings support the output shaft. This is a servo component for integration into a larger assembly.
The servo occupies 40x20x37.8mm and weighs 72g, with a 25T, Φ5.9mm output spline defining its mechanical connection. Its electrical configuration uses PWM control and a 4.8-7.4V supply range. At 7.4 V, stall torque is 30kg·cm, no-load speed is 0.15sec/60°, and stall current is 5000 mA; these ratings retain their distinct operating conditions. Travel is 180°, ingress protection is IP42, and operating temperature spans -10 to 50°C. Customization is supported for travel angle, signal/protocol and ingress protection.
