Structure, brushless motor and a brush is similar, also have the rotor and stator, and only has the structure of the brush motor instead; With brush motor rotor winding, and the power output shaft is linked together, the stator is permanent magnet steel; Brushless motor rotor is a permanent magnet steel, along with shell and output axis is linked together, the stator is winding coil, to remove a brush motor commutator brush to alternating electromagnetic field, so called brushless motor (无刷电机), that have a problem now, did not have the electromagnetic field transformation, how to make the brushless motor rotation? Rely on, in short, change the input to the brushless motor stator coil of alternating current wave frequency and waveform, the winding coil around a rotating magnetic field, electrical geometry axis on the magnetic field to drive the rotor permanent magnet steel, motor turned up and the performance of the motor and the number of magnetic steel, magnetic steel, magnetic flux intensity, and the size of the motor input voltage and other factors, more with brushless motor control performance has much to do, because the input is the direct current, current need electronic governor turned it into three phase alternating current (ac), also need to receive control signal from the remote control receiver, control motor speed, to meet the needs of the model using. In general, the structure of the brushless motor is relatively simple, really determine its performance or brushless electronic governor, good electronic governor needs a single chip microcomputer control program design, circuit design, the overall control of complex processing technology such as process.
