Product overview
The Kpower MM4000 is a standard digital servo for powered positioning in RC equipment, with applications including model aircraft and delivery drones. It is also intended for 1/5-scale RC cars, fishing bait boats and smart cat beds. Its physical architecture combines a plastic case, metal gearing and a DC brushed motor. Two ball bearings support the gear mechanism, while a long-life potentiometer provides position sensing. The product is a servo component for integration into a larger assembly.
Integration space is defined by a 65.7x30x59mm body, a weight of 148g (5.22oz), and a 25T spline measuring Φ7.8mm. Electrical specifications include a 4.8-8.4V supply range and 6000mA stall current, with PWM, UART-TTL and RS-485 listed as signal and protocol options. The servo has 50kg·cm stall torque and a no-load speed of 0.15sec/60°. Travel is 120°, ingress protection is IP42, and customization is supported for both. Its operating temperature range is -10–50°C.
