Product overview
The Kpower MM1500 is a digital servo intended for motion control in RC models, robots, smart-home equipment and drones, with delivery drones among its listed applications. Its physical architecture combines a DC brushed motor, metal gearing, a potentiometer position sensor and a 2BB bearing configuration inside a plastic and aluminum-alloy case. The body measures 40.2 × 20 × 39.5 mm and weighs 60 g, providing concrete dimensions and mass for allocating installation space. Its output interface is a 25T, Φ5.88 mm spline.
Electrical integration requires a 4.8–7.4 V supply and PWM control, with digital and analog PWM communication supported. At 7.4 V, stall torque is 22 kg·cm, no-load speed is 0.28 s/60°, and stall current is 3200 mA; these are distinct operating measurements. Travel is 180°, with customization supported for travel angle, signal protocol and ingress protection. The specified protection rating is IP42 and operating temperature is -10–50°C. Position feedback and stall protection are optional functions, so they are not standard included capabilities.
