Product overview
The Kpower HBL045 is a standard brushless servo for RC model aircraft. Its physical architecture combines a plastic and aluminum-alloy case with metal gearing, a brushless motor, a 2BB bearing configuration and potentiometer position sensing. The body measures 40x20x39.4mm and weighs 65g (2.29oz), providing concrete dimensions and mass for installation planning. Its output spline is specified as 25T with a Φ5.85mm diameter, defining the mechanical interface to account for when selecting an output attachment.
The listed configuration uses PWM control and provides 180° travel, with customization supported for both control protocol and travel angle. The voltage range is 4.8-7.4V. At 7.4 V, stall torque is 5kg·cm, no-load speed is 0.07sec/60°, and stall current is 3200 mA; these figures retain their distinct load conditions. Environmental limits are an operating temperature of -10–50°C and an IP42 protection rating, with customization also supported for protection. These electrical, mechanical and environmental specifications define the servo component for integration.
