Portescap 13N88 Brush DC High Efficiency Electric Motor 13N88-110.1

The 13N88 series is a brush DC motor featuring precious metal commutation and ironless construction, designed for high efficiency and compact applications. It operates at nominal voltages of 6, 12, or 24 V with a no-load speed of 12,400 rpm and a no-load current of 13.6 mA at 12 V. The motor delivers a maximum continuous torque of 3.3 mNm and a maximum continuous speed of 9,000 rpm, achieving up to 77% efficiency. It has a terminal resistance of 13.7 Ω, a torque constant of 9.10 mNm/A, and a rotor inertia of 0.33 g·cm². The motor measures 13 mm in diameter, weighs 18 g, and operates from -30°C to 85°C. It uses sleeve bearings with a radial load capacity of 1.5 N and axial load capacity of 150 N at 5 mm from the bearing. The commutation consists of nine segments.
