Low Noise Fan Design

Xcelaero fans are designed with a multi-disciplinary approach focused on aerodynamics, acoustics, and electromechanics. Xcelaero has been developing low noise air movers for two decades for the aerospace and defense market. Fan noise is minimized at the source. This includes a design to minimize aerodynamic noise, motor noise, and structure-borne noise. Design goals include:

  • High Efficiency
  • Clean Intake Flow
  • Blade and Vane Count for Rapid Mode Decay
  • Motor Geometry for Low Current Ripple, Cogging Torque and Torque Ripple
  • Mechanical Design and Material Choices for Low Structure Borne Noise
