D2E146-AP47-C3 DescriptionThe D2E146-AP47-C3 is a compact, high-performance external rotor motor fan (often referred to as a "motorized impeller") from the renowned German manufacturer ebm-papst. Part of the AxiForce series, it is designed to combine a powerful motor with an efficient axial impeller in a single, integrated unit. This fan is engineered for applications requiring high airflow and static pressure in a space-saving format, often used for spot cooling, cabinet ventilation, or as a component in larger heat exchange systems. Its brushless DC (EC) technology ensures high energy efficiency, variable speed control, and reliable, maintenance-free operation.
D2E146-AP47-C3 Features
Energy-Efficient EC Technology: Incorporates an electronically commutated (EC) external rotor motor, offering significantly higher efficiency compared to traditional AC motors, leading to lower energy consumption and operating costs.
Integrated Motor & Impeller: The external rotor design integrates the motor directly with the impeller blades, creating a compact, lightweight, and robust unit with excellent power density.
Intelligent Speed Control: Features integrated electronics for smooth, continuous speed control via a standard PWM (Pulse Width Modulation) or 0-10 V DC input signal, allowing for precise airflow adjustment based on thermal demand.
Reliable & Maintenance-Free: The brushless DC motor design eliminates brush wear, ensuring a long service life with no maintenance required under normal operating conditions.
Advanced Blade Design: The aerodynamic AxiForce impeller blades are optimized for efficient airflow with low noise generation, providing a favorable balance between performance and acoustic comfort.
Built-in Protection: Typically includes protection features such as locked-rotor protection, overcurrent protection, and thermal overload protection for enhanced operational safety and durability.
D2E146-AP47-C3 Materials & Applications
Materials: The housing and impeller are typically constructed from high-quality, glass-fiber reinforced plastics (PBT or similar) for excellent strength, light weight, and corrosion resistance. The motor features high-grade magnetic materials, copper windings with Class B or F insulation, and long-life ball bearings or sleeve bearings for quiet operation.
Applications: Ideal for applications requiring directed, high-pressure airflow in compact spaces, including:
Electronic cabinet and control panel cooling
Spot cooling of power electronics, drives, or transformers
Ventilation in telecommunications and IT equipment
Integration into air handling units (AHUs) or fan coils
Medical equipment and laboratory devices
Professional food service equipment
