The B2040N2B is a brushless DC motor with an inner rotor, slotless design, and sensorless commutation, designed for precision drive applications in medical equipment and industrial automation. It is available in 12V and 9V variants, with a 20mm diameter and 40mm length, weighing 55g. The motor has a maximum output power of 31W, a no-load speed of up to 15000 rpm, and a stall torque of 79.6 mNm at 12V. It features a thermal class of 155°C, operates from -40°C to +100°C, and has an IP20 protection rating. The rotor inertia is 2 gcm², with dual ball bearings and axial and radial play specified at 0.012mm and 0.008mm respectively. The motor supports optional lead wire lengths, shaft lengths, gearheads, and encoder drivers.
