Brushless motor VS motor with carbon brush
Brushless motor VS motor with carbon brush
  BLDC motor change the alternating frequency and waveform by changing the input to the brushless motor stator coil current wave,BLDC motor form a magnetic field around the geometry of the motor with coils winding, this magnetic filed drive the BLDC motor rotor 's permanent magnet rotating, then the motor rotate.
The BLDC motor performance is related to The number of magnetic intensity, magnetic flux, magnetic motor input voltage, also the control performance, because BLDC use the direct current as input, the direct current of BLDC motor requires an electronic governor to turn 3phase alternating current and need to receive the control signal from the remote control receiver.BLDC motor contorl the rotate speed of motor to meet the needs of the model.
BLDC motor have a simple construction,to determine the performance of brushless motoris brushless electronic governor,a good electronic governor needs to have a single chip microcomputer control program design, circuit design, complex machining process, the overall control of the process, and that's why BLDC motor is costly than motor with carbon brush.
