Portescap 13N88 Brush DC High Efficiency Electric Motor 13N88-107.1

The 13N88 brush DC motor is a high-efficiency, precision motor with precious metal commutation, designed for applications requiring continuous torque up to 3.3 mNm and maximum continuous speed of 9,000 rpm. It operates at nominal voltages of 6, 12, or 24 V, with the 107 variant specified for 12 V operation, delivering a no-load speed of 12,400 rpm and a terminal resistance of 13.7 Ω. The motor achieves 77% maximum efficiency and has a rotor inertia of 0.33 g·cm². Its ironless design, 9-segment commutation, and sleeve bearings support long life in compact applications. The housing measures 13 mm in diameter with a shaft length of 10 mm, and the unit weighs 18 g. Operating temperature ranges from -30°C to 85°C, with a maximum rotor temperature of 100°C. Maximum radial shaft load is 1.5 N at 5 mm from the bearing, and axial shaft play is 0.15 mm.
