Product Specifications

Technical details and manufacturing context for Cooling Fan

Definition
A cooling fan is an essential component of an industrial electromagnetic clutch-brake unit, responsible for forced air convection to remove excess heat generated during electromagnetic engagement, disengagement, and slippage. It prevents thermal overload, maintains optimal operating temperatures, and ensures the reliability and longevity of the clutch-brake assembly.
Working Principle
The fan is typically mounted on a rotating shaft within the unit. As it spins, it draws cooler ambient air across heated components (like the electromagnetic coil, armature, and friction surfaces) and expels the warmed air, facilitating continuous heat exchange through forced convection to maintain a stable thermal equilibrium.
Common Materials
Aluminum Alloy, Engineering Plastic (e.g., PBT, Nylon)
Technical Parameters
  • Fan diameter, determining airflow capacity and physical fit within the clutch-brake housing. (mm) Per Request
Components / BOM
  • Impeller/Blades
    Rotates to create airflow and pressure differential for moving air.
    Material: Aluminum Alloy or Engineering Plastic
  • Motor Hub
    Houses the electric motor that drives the impeller rotation.
    Material: Steel or Aluminum Alloy
  • Bearing
    Supports the rotating shaft of the impeller, minimizing friction.
    Material: Steel (with lubricant)
Engineering Reasoning
600-1800 RPM at 24V DC, 0.5-1.2 m³/min airflow, 40-80°C ambient temperature
Bearing seizure at 200°C lubricant temperature, blade deformation at 2200 RPM centrifugal force exceeding 15 N
Design Rationale: Grease thermal breakdown at Arrhenius rate constant k=1.2×10⁻⁵ s⁻¹ above 150°C, followed by boundary layer separation at Reynolds number Re>5×10⁴ causing aerodynamic stall
Risk Mitigation (FMEA)
Trigger Electrostatic discharge accumulation exceeding 8 kV on polycarbonate blades
Mode: Dielectric breakdown creating conductive carbonized tracking paths
Strategy: Embedded conductive carbon nanotubes at 0.3% weight concentration providing 10⁶ Ω·cm resistivity
Trigger Axial preload loss below 5 N·m due to thermal expansion mismatch (Δα=12×10⁻⁶ K⁻¹)
Mode: Angular contact bearing skidding generating 120 dB vibration at 3 kHz
Strategy: Belleville washer stack maintaining 8±0.5 N·m preload across -20°C to 120°C range
