The BO2814N2B is an outer rotor, sensorless brushless DC motor designed for UAV and aeromodelling applications. It has a diameter of 28mm and an overall length of 14.3mm, with a weight of 21g and a rotor inertia of 12gcm². The motor supports 12V, 24V, and 36V variants, with a no-load speed of 15300 rpm across all voltages and a maximum output power of up to 84W. It features two ball bearings, an IP20 protection rating, and operates within a temperature range of -40°C to +120°C. The motor has 7 pole pairs and uses electronic sensorless commutation. Thermal resistance values are 2.5K/W for housing-to-ambient and 2K/W for winding-to-housing, with a winding thermal class of 180°C. Axial and radial plays are specified at 0.014mm and 0.008mm respectively.
