The Kpower DMM150 servo motor provides controlled movement for robotic arms, robots, remote-control cars and toys. Its brushed motor, metal gears and semi-aluminum construction suit compact motion-control assemblies, while position feedback and stall protection support control-system integration. Specified stall torque is 15.5 ± 0.20 kg·cm at 4.8 V and 18.0 ± 0.20 kg·cm at 6.0 V, with 120° ± 3° travel.
Features
Wear-resistant metal gears made from copper and aluminum.
Semi-aluminum construction with a 7075 aluminum middle case.
Brushed motor and long-life potentiometer.
Position feedback and stall protection.
PWM, TTL and RS485 interface support; the supplied interface configuration is unspecified.

Applications
Robotic arms and robot mechanisms: actuate joints or linkages within the specified 120° ± 3° travel, with position feedback available for control integration.
Remote-control cars: operate steering linkages using the servo's controlled angular travel and metal gear train.
Toys: drive moving mechanisms with a compact 40 × 20 × 40 mm servo assembly.
The DMM150 is designated a 15kg medium servo; the headline does not specify a torque unit or test condition.
