2. Grundlegende technische Spezifikationen

3. Anwendungsbereich
4. Main cooling fan for ABB ACS800 high-power inverters (Frame R7)

ABB spare part No.: 64650424

2. Forced air cooling of high-power industrial drives, SVG, high-power UPS and industrial cabinets
3. High-static-pressure air supply for HVAC and industrial equipment
4. Installation & Verkabelungsrichtlinien
5. Equipped with terminal block for three-phase AC power supply; DO NOT run directly on single-phase 220V power.
6. Built-in thermal protection contact; the inverter monitors this circuit and triggers a fan fault if overheating or wire breakage occurs.
7. Montageausrichtung: align the scroll outlet with the inverter radiator; flange mounting holes match the ACS800 cabinet.
8. Regular dust cleaning is mandatory; clogged dust causes airflow degradation, overheating and premature bearing failure.
9. Cross-Series Comparison & Ersatzoptionen
10. Equivalent model: D2D160-CE02-11

Same 700W power, 1.9Eine Strömung; different winding and terminal assignment. Not plug-and-play without rewiring.

2. Factory long-life upgraded replacement: R3G225-RE07-25 (EC fan, official ABB maintenance spare). Requires modification of wiring and fault feedback circuit.
3. Domestic replica versions: Niedrigere Kosten, but inferior bearing service life, dynamic balance and TCO reliability compared with original units; only suitable for non-critical operating conditions.
4. Allgemeine Fehlerbehebung
5. Fan fails to start after power-up

Verify three-phase power supply and tight terminals; test TCO thermal cutout. An open TCO indicates thermal burnout and fan replacement is required.

2. Ungewöhnliches Geräusch & starke Vibration

Impeller dust buildup causing imbalance; Lagerverschleiß; impeller rubbing against scroll housing.

3. Inverter reports fan fault

Fan stall / open TCO circuit; broken wiring; insufficient rotational speed.

4. Insufficient airflow & frequent inverter overtemperature alarms

Clogged filter/radiator; speed decay; Laufradverschleiß.

7. Wartung & Ersatzhinweise
8. Always order the full part number D2D160-BE02-11. Das Suffix 11 cannot be replaced with 12/14, otherwise mismatched pinout will lead to component damage after power-on.
9. Cut power and discharge DC bus residual high voltage before replacement (ACS800 carries high DC residual voltage).

Operating Principle of D2D160-BE02-11 (ebmpapst 3-phase AC External Rotor Double-Inlet Forward-Curved Centrifugal Fan)

The assembly consists of three core components: 3-phase external rotor asynchronous motor + double-inlet forward-curved multi-blade centrifugal impeller + scroll housing. It works by electromagnetic drive combined with centrifugal aerodynamics, serving as the primary cooling fan for ABB ACS800 inverters.

Teil 1: Motor Principle – 3-Phase External Rotor Asynchronous Motor

Conventional motors have stator outside and rotor inside; this fan adopts the reversed external rotor structure:

The stator is fixed in the central hub; the rotor with the impeller rotates around the fixed stator.

When three-phase alternating current flows into the stator winding, a rotating magnetic field is generated, inducing eddy currents inside the rotor cage. The electromagnetic torque drives the rotor and impeller to rotate.

Vorteile: Kompakte Struktur, short overall length, hohe Steifigkeit, directly coupled to the impeller without a separate shaft coupling.

Teil 2: Airflow Principle – Centrifugal Air Intake & Pressurization

1. Air enters axially from both sides (double inlet) of the impeller.
2. The high-speed rotating forward-curved blades throw air outward radially under centrifugal force, increasing air pressure and velocity.
3. The spiral scroll housing collects the high-speed airflow, converts kinetic energy into static pressure, and delivers concentrated high-pressure airflow out through the rectangular outlet to blow across the inverter heat sink.

Model Interchange Summary

1. Original model D2D160-BE02-11: Only interchangeable with BE02-11. BE02-12/14 or CE02-11 cannot be fitted directly.
2. Original model D2D160-CE02-11: Only interchangeable with other CE02 suffix variants.
3. The two-digit suffix only defines terminal pinout + TCO protection circuit. Luftstrom, static pressure and rotational speed remain identical (2700 U/min, 700W).
