The 25**C9…M… micro DC servo motor series features a 25 mm diameter, coreless brushed architecture for high efficiency and precise motion control. Rated voltages from 12 V to 30 V, stall torques up to 196.9 mNm, and low-noise performance make these motors ideal for medical devices, robotics, and precision instruments. Encoder and gearbox options enable advanced feedback and high torque adaptation.
