DC Fan brushless products works principle

In simple terms, "DC Fan" by changing the input current to alternating wave frequencies and wave brush-less motor stator coil in the motor windings is formed around a full turn around the geometric axis of the magnetic field, the magnetic field on the rotor drive forever magnetic rotating magnet, the motor will turn up, performance and the number of magnets, magnet flux intensity, motor input voltage size and other factors "DC Fan" motor-related, but have a great relationship with the brush-less motor control performance, because the input is DC current require electronic speed governor to turn it into a three-phase alternating current, but also from the remote control receiver which receives the control signal to control the motor speed to meet the need to use the model. In general, the structure of the brush-less motor is quite simple, really determine its performance or brush-less electronic governor, "DC Fan" good electronic governor requires SCM program design, circuit design, complexity the overall control process and other processes, so the price is higher than the brush motor lot.
