Hobbywing Ezrun BL Motor 2030 5200kV 1/18

Sensorless brushless motor for 1:16/1:18 touring cars and buggies. Dimensions: 30 mm (L) x 20 mm (Ø). Motor type: Brushless. No-load speed per volt: 5200 kV. Output power with an efficiency of up to 85%. High-quality craftsmanship and intelligent design. The motor housing is made of hard, anodized aluminum. The motor windings are made of oxygen-free, double-insulated copper wire. Additionally, the advanced rotor structure withstands high temperatures. The motor shaft is made of high-quality, polished steel, and precision ball bearings ensure extremely smooth operation. This results in outstanding performance, long lifespan, and exceptional smoothness. Furthermore, it can be easily connected to a controller thanks to the round head connectors.

A brushless motor is an electric motor without brushes, which offers higher efficiency, lower wear, and reduced weight compared to brushed motors. In sensorless brushless motors, the rotor's position is determined by the back EMF generated in the stator coils during induction, which is evaluated by the electronic control circuit. Since a minimum speed is required to evaluate the back EMF, sensorless brushless motors run blind until that speed is reached.
