The Brushless EC Centrifugal Blower Fan greatly simplifies the structure because the collector rings and brushes for excitation are omitted. At the same time, not only the manufacturability of the fan is improved, but also the mechanical reliability of the fan operation is greatly enhanced, and the service life is increased.

Brushless EC Centrifugal Blower Fan manufacturers tell you that at the same time, the air gap magnetic density can be greatly improved, and the fan index can be optimally designed. The direct effect is that the fan volume is reduced and the weight is reduced. Not only that, compared with other fans, it also has very excellent control performance.
1. Due to the high performance of permanent magnet materials, the torque constant, torque inertia ratio and power density of the fan are greatly improved. Through reasonable design, the indicators such as moment of inertia, electrical and mechanical time constants can be greatly reduced, and the main indicators of servo control performance have been greatly improved.
2. The design of the modern permanent magnet magnetic circuit has been perfected, and the coercive force of the permanent magnet material is high, so the Brushless EC Centrifugal Blower Fan
The anti-armature reaction and its anti-demagnetization ability are greatly enhanced, and the control parameters of the fan are greatly reduced with the influence of external disturbances.
3. Since the electric excitation is replaced by a permanent magnet, the design of the excitation winding and the excitation magnetic field is reduced, thereby reducing the excitation magnetic flux, excitation winding inductance, excitation current and many other parameters, thereby directly reducing the controllable variables or parameters. Combining the above factors, it can be said that the Brushless EC Centrifugal Blower Fan has excellent controllability.
