Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated high speed motor for drone, or synchronous DC motors, are sensored brushless motor powered by DC electricity via an inverter or switching power supply which produces an AC electric current to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor.

Powerful brushless motor exhibit reduced energy use, long life, low noise, compact size and light weight characteristics.

Choosing a good high power brushless motor can be easy and difficult at the same time. There's a few things to take in consideration when choosing one high speed brushless motor for your plane:
