Working Principle

The 9WP1212M1021 operates on the principle of brushless DC, which consists of using a three phase stator and a rotor for the active components. The stator is made up of three windings that generate a rotating magnetic field in the air gap. The rotor has three coils, each one carrying currents that are supplied by the stator. The construction of the rotor is such that the currents create a field that is constantly rotating around the rotor.

As the magnetic field rotates around the rotor, the rotor is forced to rotate in the same direction. This rotation can easily be converted into mechanical work, providing the necessary air flow. The level of air flow can be regulated by controlling the speed at which the magnet rotates around the rotor. The 9WP1212M1021 is able to operate at both low and high speeds, making it an ideal choice for a wide range of applications.
