Industrial Axial Fan

The Fans M2D068-CFMotor is an ebmpapst axial fan built for forced electronic cooling in industrial equipment. It serves engineers maintaining Siemens servo spindle systems or similar 400 V environments. The compact external-rotor design fits tight enclosures while delivering high airflow.

35000 m³/h Airflow at 2750 RPM

At 400 V and 89 W the fan moves up to 35000 m³/h, providing strong headroom for heat-exchanger duty and dense component cooling. Speed drops below 2750 RPM when load increases or voltage sags, reducing airflow accordingly. The 0.26 A draw leaves margin on typical 400 V supply circuits.

100 % Speed Control via Analog or Serial Interface

The integrated EC electronics accept 0–10 V or PWM signals and serial commands for full 0–100 % speed regulation. No separate controller is required; the fan starts and runs directly from the matched motor electronics. Buyers needing fixed-speed operation or a different control voltage cannot use this model.

Questions about this item

Will the 400 V axial fan run alongside the 68 W power supply already in my Siemens cabinet?

The fan draws 89 W at 400 V and 0.26 A, so the existing 68 W supply would be undersized; a supply rated for at least 100 W on the 400 V rail is needed.

How do I verify the fan is operating at the specified 2750 RPM after installation?

Connect the fan to its 400 V feed and measure speed with a tachometer or the servo drive’s feedback; it should read 2750 r/min when the GreenTech EC control signals full speed.

Does the M2D068-CFMotor ship with mounting brackets, power cable or a GreenTech EC controller, or must I source them separately?

The box contains the axial fan unit only; mounting hardware, 400 V power cable and any analog or serial speed-control interface are not included and must be purchased separately.
