Product overview
The Kpower P0037 is a miniature servo component for drone, RC, robot and smart-home mechanisms. Its physical architecture combines a plastic housing, self-lubricating POM gears and a 3.3W coreless hollow-cup motor, with a potentiometer for position sensing. The body measures 20x8.4x24.4mm and weighs 3.7g (0.13oz), providing a compact integration envelope. A 20T Φ3.45 spline defines the mechanical output connection, while the standard three-wire JR interface provides the electrical control connection.
The standard control arrangement uses PWM and a default travel angle of 120°, with customization supported for both travel and signal protocol. The operating supply range is 3.7-6.0V. At 6.0V, stall torque is 800 gf·cm, no-load speed is 0.06 s/60°, and stall current is 700 mA; these values retain their separate load conditions. Operating temperature is -10～50°C. The specified ingress-protection rating is IP42, with customization supported, making that rating a material integration constraint.
