Brushless motor changes the input to the brushless motor stator coil’s current wave frequency and waveform, forming a magnetic field around a geometric axis of rotation of the motor winding coil to drive the permanent magnet rotor rotation, so the motor will turn up.

The quantity, performance and magnetic motor magnetic flux intensity, motor input voltage and other factors related greatly with the performance of brushless motor control. Because the input is the DC current and the electronic governor needs to turn the current into a three-phase alternating current and receive a control signal from the remote control receiver in order to control motor speed and meet the needs of the model.

In general, the structure of the brushless motor is relatively simple and the important thing is the brushless electronic governor. A good electronic governor need microcontroller program design, circuit design and complex processing technic, so the price of brushless motor should be much higher than the brush motor.
