Product overview
The Kpower MM0300 is a digital positioning servo for applications including RC model aircraft, robot joints, industrial automation and STEAM education. Its physical architecture combines a DC brushed motor, metal gearing, two ball bearings and potentiometer position sensing within a plastic and aluminum-alloy case. The integration envelope is 40x20x37.5mm, with a weight of 58g (2.05oz). A 25-tooth, Φ6mm spline defines the mechanical output interface, while PWM provides the control signal for the specified configuration.
Electrical integration requires a supply within 4.8-8.4V and consideration of the specified 2500mA stall current. The MM0300 has a stall torque of 4.5kg·cm and a no-load speed of 0.12sec/60°; these figures describe different operating conditions. Travel is 180°, with customization supported for travel angle, signal and protocol, and ingress protection. The specified protection rating is IP42, and the operating temperature range is -10 to 50°C. These limits define the environmental conditions for incorporating the servo into an aircraft or other mechanism.
