Axial fan, centrifugal fan, and electronic equipment employing one of these fans
The Journal of the Acoustical Society of America, 2003A low-noise axial fan is provided with whirring sound minimized. The axial fan includes a plurality of blades arranged around a rotation axis at predetermined layout pitches. The blades are arranged at varied layout pitches. For instance, the layout pitch between the two adjacent blades may be different from the layout pitch between the remaining ...

Static Balancing of Centrifugal Fan
IOSR Journal of Mechanical and Civil EngineeringCentrifugal fans are critical in cement manufacturing for airflow regulation and dust management but often suffer from vibration-related faults due to harsh operational conditions. Excessive vibration, commonly caused by rotor unbalance and misalignment, can lead to premature component failure.

The family of energy-saving centrifugal fans
2016 13th Selected Issues of Electrical Engineering and Electronics (WZEE), 2016The paper presents three centrifugal fans withlow power consumption. The fans are equipped with a new drive system consisting of a brushless DC motor and power electronics system (inverter) used for motor control. The construction of the motor required much less iron and copper than the present motors. The principle of sensorless control of inverter is

Centrifugal Fan Performance With Inlet Clearance
Journal of Engineering for Gas Turbines and Power, 1984This paper describes a systematic study of the influence of the inlet clearance gap on the performance of a centrifugal fan. Overall fan performance in terms of volume flow rate, pressure rise, stall margin, and efficiency were measured over a range of values of the radial clearance between the impeller and the stationary inlet cone.
