Product Specifications

Technical details and manufacturing context for Fan Motor

Definition
A specialized electric motor designed specifically to power cooling fans by rotating fan blades, creating airflow for ventilation, cooling, or exhaust purposes. It serves as the core driving component within cooling fan assemblies, determining the fan's performance characteristics including airflow rate, pressure, and efficiency.
Working Principle
Operates on electromagnetic principles where electrical current flowing through windings creates a rotating magnetic field. This field interacts with permanent magnets or induced magnetic fields in the rotor, causing it to rotate. The rotational motion is transferred to the fan shaft, which drives the attached blades to move air.
Common Materials
Copper windings, Silicon steel laminations, Permanent magnets (e.g., neodymium), Aluminum or steel housing, Bearings (ball or sleeve)
Technical Parameters
  • Rated power input indicating electrical consumption and output capability (W) Standard Spec
Components / BOM
  • Stator
    Stationary part containing windings that create rotating magnetic field
    Material: Silicon steel laminations with copper windings
  • Rotor
    Rotating part that converts magnetic force into mechanical rotation
    Material: Steel shaft with permanent magnets or copper bars
  • Bearings
    Support rotation and reduce friction between moving parts
    Material: Steel balls with lubricant or sintered bronze
  • Housing
    Protects internal components and provides mounting structure
    Material: Aluminum alloy or steel
Engineering Reasoning
0.5-2.5 kW, 1000-3000 RPM, 85-240 VAC, 50-60 Hz
Winding temperature exceeds 155°C (Class F insulation limit), bearing vibration exceeds 4.5 mm/s RMS, shaft imbalance exceeds 0.4 g·mm/kg
Design Rationale: Insulation breakdown due to thermal aging (Arrhenius equation: degradation rate doubles per 10°C rise above 155°C), bearing fatigue from Hertzian contact stress exceeding 1.8 GPa
Risk Mitigation (FMEA)
Trigger Single-phasing in 3-phase supply (phase loss > 200 ms)
Mode: Overheating and winding insulation failure within 15 minutes
Strategy: Phase-loss protection relay with 150 ms detection threshold
Trigger Lubricant degradation (viscosity drop below ISO VG 32 at 40°C)
Mode: Bearing seizure at > 1.2 MN/m² contact pressure
Strategy: Sealed-for-life bearings with lithium-complex grease (NLGI 2 grade)
