Product overview
The Kpower MB0090 is a miniature servo for fixed-wing drones, RC model aircraft, medical equipment and other listed applications. Its physical architecture combines a plastic case, machine-finished metal gears, a DC brushed motor, a potentiometer position sensor and a 1BB bearing arrangement. The gears have stated backlash below 0.5°. Programmable electronic protection and soft start/stop provide additional control functions. This is an actuator component for integration into a larger assembly, with a compact housing measuring 22.8x12.4x28.3mm.
Integration requires a 3.7-6V supply and PWM control. At 6.0V, stall torque is 3kg·cm, no-load speed is 0.08sec/60°, and stall current is 1000 mA. Travel is 180°, with customization supported for travel, signal/protocol and ingress protection. The specified protection rating is IP42, and operating temperature is -10 to 50°C. Procurement details contain two material inconsistencies: the 9G designation accompanies a specified weight of 13g, while the feature list describes a 25T spline and the specification gives 20T Φ4.76mm.
