The ebm-papst M4Q045-CA03-51/A64 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, 34 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 stated operating record provides an audit trail for installed equipment while keeping the duty point central.
Correct sizing and operation within documented limits can reduce avoidable thermal stress and maintenance events; project savings require duty-cycle analysis.
It can be evaluated for demanding service using the documented ratings, installation limits and preventive-maintenance plan for the application.
The supplied table lists 1,550 rpm; use the exact datasheet for the complete operating curve.
