Structure, brushless motor controller and a motor controller and the rotor and stator have similarities, but there is structure and brush motor controller instead. A brush rotor is connected to the power output shaft of the motor controller of coil winding, the stator is permanent magnets. Brushless motor controller of rotor is a permanent magnets, it connected to the output shaft and shell. The stator windings. Brushless motor controller used for alternating electromagnetic field commutator brush has been removed, so called the brushless motor controller. Now there is a problem. No electromagnetic field, conversion brushless motor controller can rotate? In short, by changing the input to the stator winding brushless motor controller of the current wave of ac frequency and waveform, formed around the windings around the motor controller geometry axis of rotating magnetic field. The magnetic drive the permanent magnets on the rotor rotates, the motor controller. The performance of the motor controller and magnetic steel, magnetic steel, magnetic flux intensity and the number of the input voltage of the motor controller, also associated with the control performance of the brushless motor controller. Because the input is a direct current, the current need through the electronic governor into three-phase alternating current (ac), and also need from the remote control receiver control signal to control the motor speed controller, in order to meet the requirements of the model. In general, the structure of the brushless motor controller is relatively simple. Its performance is the real determinant brushless electronic governor. A good electronic governor needs single-chip microcomputer control program design, circuit design, control the overall process, such as complex processing technology.
