Product overview
The Kpower HBL090 9kg half-aluminium metal-gear brushless standard servo is an actuator for fixed-wing drones, desktop robotic arms, industrial automation and service robots. Its physical architecture combines a brushless motor, metal gearing with impact-resistant reinforced steel teeth, and a plastic-and-aluminum-alloy case with an aluminum middle shell. The 40x20x39.4mm body weighs 65g (2.29oz), providing concrete dimensions and mass for installation planning. Its mechanical interface uses a 25T spline with a 5.85mm diameter, while the bearing specification is 2BB.
The standard control configuration combines PWM signaling with potentiometer position sensing and 180° travel. Customization is supported for travel angle, signal/protocol and waterproofing, with custom magnetic encoding also offered. Electrical integration requires 4.8-7.4V; at 7.4 V, stall torque is 13kg·cm, no-load speed is 0.1 s/60°, and stall current is 5500 mA. The operating temperature range is -10 to 50°C and the protection rating is IP42. The servo carries an up-to-one-million-operating-cycle claim.
