Description
The ebmpapst M4Q045-BD01-01/A09 is a precision-engineered 4-pole shaded pole motor designed specifically for the rigorous demands of commercial refrigeration thermodynamics. Representing Original Engineering from ebmpapst Germany, this Q-motor series utilizes a square design architecture to maximize heat dissipation and mounting versatility within restricted plenum spaces. The unit operates on a single-phase 230V AC supply, delivering a shaft power output of 5W while maintaining high efficiency across a 50/60Hz frequency range. Engineered for continuous duty cycles, the motor features impedance protection to prevent winding burnout during locked-rotor scenarios, ensuring long-term reliability in critical cold chain environments. Technical Compatibility is guaranteed for standard supermarket freezer condensers, evaporator units, and bottle coolers requiring a robust 1300/1550 RPM airflow profile. The sintered oil-impregnated bearing system ensures low-noise operation and extended service intervals, minimizing maintenance downtime. Current Lead Time and availability should be verified for MRO planning.
