Description
ebm-papst R1G133-AA65-02 (also known as R1G133AA6502) is a high-efficiency 133 mm single-inlet backward-curved EC motorized impeller powered by an integrated M1G055-BD brushless DC motor. Measuring 133 mm in diameter by 91 mm in depth (5.24 in × 3.58 in), it delivers an aerodynamic airflow of 212.0 CFM (360.2 m³/h) at a nominal speed of 3900 RPM on a 48 VDC supply. Engineered for continuous S1 industrial duty, the assembly features a 7-blade PA66 fiberglass-reinforced impeller, die-cast aluminum electronics housing, thick-layer passivated rotor, and precision dual ball bearings. Electrical interface is established via four AWG20 wire leads with crimped brass tips, offering integrated 0–10 VDC/PWM speed control, tachometer output, locked-rotor protection, and reverse-polarity safeguarding.
Key Features
- Electronically Commutated Motor: Features integrated brushless M1G055-BD DC motor technology for low power draw and superior thermal efficiency.
- Fiberglass-Reinforced Impeller: Aerodynamic 7-blade PA66 composite construction withstands elevated static pressures with minimal acoustic turbulence.
- Flexible Speed Modulation: Supports linear 0–10 VDC and high-frequency PWM inputs alongside open-collector tachometer feedback.
- Comprehensive Motor Protection: Built-in circuitry defends against reverse supply polarity, locked rotors, and motor current overload.
- Industrial Duty Design: Dual precision ball bearings and passivated rotor enable arbitrary mounting orientations across demanding continuous-run environments.

Applications
ebm-papst R1G133-AA65-02 backward-curved motorized impellers are primarily integrated into high-density telecommunication base stations, power distribution rectifiers, and modular server rack plenums requiring compact, non-ducted airflow displacement. They serve as essential active cooling components within industrial automation cabinets, automated test benches, and medical lab diagnostic centrifuges where quiet, variable-speed heat extraction is mandated. Furthermore, this motorized impeller is widely deployed for MRO retrofits in compact building ventilation units, cleanroom fan filter assemblies, and electronic enclosure heat exchangers.
