AC Capacitor Motor for Quiet, Reliable Fan Applications

The CP80-18UAC AC capacitor motor is engineered for high-efficiency fan operations in commercial and industrial environments. Operating at 120V 60Hz, this quiet fan motor delivers 33W rated output with ultra-low noise levels and dependable continuous duty motor performance.

Its 4-pole, capacitor-run configuration (3.0μF/250V) ensures a smooth 1520 RPM operation under load with a wide operating voltage range (starting voltage ≤95V). Built to insulation class A and duty cycle S1 standards, this motor withstands 1800V AC dielectric stress and resists leakage below 5mA.


Quiet Fan Motor with High Safety and Energy Efficiency

The AC capacitor motor is tested for no-load power ≤22.5W and rated power of 32.5W±10%, supporting energy-saving goals in HVAC systems, industrial ventilation, and household appliances. Its sound level remains ≤45dB(A) at 30cm, ensuring minimal noise impact in enclosed environments.

Robust safety mechanisms include:

  • Dielectric Strength: 1800V AC for 3s

  • Insulation Resistance: ≥100MΩ (500V DC)

  • Creepage Distance: ≥2.6mm (coil-to-core)


Continuous Duty Motor Ideal for HVAC, Appliances & Labs

Built for uninterrupted operation, this continuous duty motor features a high-precision shaft with axial runout ≤0.05mm and mounting torque ≥8 kgf·cm to ensure firm, vibration-free installation. Whether used in HVAC condensers or lab fume hoods, the motor delivers stable airflow with minimal wear.

Applications include:

  • HVAC condenser fans, ceiling ventilation systems

  • Industrial exhaust and greenhouse circulation

  • Air purifiers, refrigeration units, lab exhausts
