The ebm-papst M4Q045-EF03-04 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 115 V operation, 100 W input, speed up to 1550 rpm for matching the supply and mechanical duty to the driven assembly. Its documented construction provides the basis for integration and service planning. 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 available technical basis helps align sourcing and engineering for maintenance sourcing while keeping the duty point central.
Continuous operation must remain within the published electrical, thermal and aerodynamic limits; confirm the exact datasheet and system conditions.
The supplied comparison identifies 45 mm dimensions for installation planning; review it together with the other listed ratings rather than as a standalone selection criterion.
The supplied table lists 115 V. Verify supply type, frequency, wiring and permissible tolerances before commissioning.

Configured for Commercial Refrigeration, the ebm-papst M4Q045-EF01-52 is a 230 V AC Q-motor, documented with a listed airflow of 1,760 m³/h. It provides a traceable selection parameter.
