The ebm-papst M4Q045-CA01-01/A30 is an AC motor for compatible fan assemblies in refrigeration cooling. It gives equipment builders a defined replacement or design-in motor rather than a complete standalone fan.
Selection data includes 230 V operation, 30 W input, speed up to 1550 rpm for matching the supply and mechanical duty to the driven assembly. The matched datasheet identifies IP42 protection for motor durability and installation review. Thermal behavior, sound and energy use depend on the complete fan system and load. Correct wiring, shaft interface and duty matching support reliable operation and long component life.
The stated operating record supports disciplined comparison across service workflows with attention to real airflow resistance.
Check for blocked airflow paths, incorrect supply, loose wiring, abnormal rotation or system resistance before consulting the exact service documentation.
Compare 45 mm, 230 V, 30 W plus mounting, connector and duty-point requirements.
Verify mounting orientation, inlet and outlet clearance, fastener security, electrical connections and the exact dimensional drawing before startup.
