Amewi Brushless motor 2435 3900 KV internal rotor

Brushless upgrade motor for Amewi Breaker Drift Truck. Dimensions: 35 mm (L) x 24 mm (Ø). Motor type: Brushless. No-load speed per volt: 3900 kV. Shaft: 2.3 mm Ø, 11.2 mm long. Sensorless. 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 operate without feedback until that speed is reached. A brushless motor is an electric motor without brushes, characterized by higher efficiency, lower wear, and reduced weight compared to brushed motors.
