Product overview
The Kpower MM0090 9G Semi-Aluminium Metal Gear Micro Servo is a positioning component for RC, robot, smart home and drone applications. Its physical architecture combines a plastics-and-aluminum-alloy case, metal gears, a DC brushed motor, a 1BB bearing arrangement and a potentiometer position sensor. The output spline is specified as 20T Φ4.85mm. Although “9G” forms part of the model name, the specified product weight is 14g (0.49oz), which is the relevant figure for integration planning.
Integration requirements include a 3.7-6V supply and PWM control, with digital and analog PWM communication supported. Dimensions are listed as 22.5x12x22.6 without a stated unit. The servo provides 180° travel, 3.4kg·cm stall torque at 6 V and a no-load speed of 0.09sec/60°. Stall current is 1400mA at 6V. Operating limits include -10 to 50°C and an IP42 rating. Customization is supported for travel, protocol and ingress protection; position feedback and stall protection are optional configuration choices.
