Hobbywing Seaking BL Motor 2848SL

Sensorless Brushless Motor. Dimensions: 48 mm (L) x 27.8 mm (Ø). Motor type: Brushless. No-load speed per volt: 3900 kV. Ideal for boat models. Operates with 2S to 3S LiPo. Water-cooled. The Hobbywing Seaking 2848SL is a brushless motor specifically designed for use in boat models, with 3900 revolutions per volt. It requires a supply voltage of 7.4 to 11.1 volts. Water cooling ensures efficient dissipation of the generated heat. A brushless motor is an electric motor without brushes, which offers higher efficiency, less wear, and lower weight compared to brushed motors. In sensorless brushless motors, the rotor's position is determined by the back EMF induced in the stator coils, which is evaluated by the electronic control circuit. Since a minimum speed is required to evaluate the back EMF, sensorless brushless motors operate without positional feedback until that speed is reached.
