Introduction to Bonfiglioli Asynchronous Motors

Three-phase asynchronous motors represent the most reliable and widespread solution for driving mechanical systems in every industrial sector. Bonfiglioli has developed a comprehensive range of electric motors designed to integrate perfectly with their own gearboxes, offering a harmonized transmission package.

Choosing the asynchronous motors from this range means focusing on a successful solution that complies with the most rigorous international energy efficiency standards. From the BN series to the BX series, every model is optimized to reduce consumption and increase productivity.

This range is the number 1 choice for those seeking constructive robustness and versatility of use. Whether for simple applications or heavy-duty work cycles, Bonfiglioli motors guarantee consistent performance over time.

Valuable Technical Characteristics of the BN, BE, and BX Series

The value of these motors lies in the breadth of the range. Bonfiglioli offers three main series, differentiated based on efficiency levels and current international regulations.

Each series is available in different polarities (2, 4, 6 poles) and can be configured with a wide range of options, such as electromagnetic brakes, encoders, and thermal protections.

Here are the main series:

• BN Series: Standard motors with IE1 efficiency, ideal for markets outside EU regulations or for specific applications.

• BE Series: High-efficiency motors complying with the IE2 standard.

• BX Series: Premium efficiency motors complying with the IE3 standard, mandatory for most industrial applications in Europe.

• Modularity: Wide choice of flanges (B5, B14) and mounting feet for total integration.

Energy Effectiveness and Operational Savings

The use of high-efficiency asynchronous motors, such as the BX series, is extremely effective for reducing corporate energy bills. In an industrial plant, electric motors absorb the majority of the energy.

Switching to a higher efficiency class is an immediate factor for economic success. Lower heat dissipation not only saves energy but also extends the service life of bearings and internal insulation.

Focusing on Bonfiglioli motors also ensures perfect compatibility with inverters. This allows for intelligent speed management, further optimizing the global efficiency of the entire transmission system.

Robust Design for Industrial Environments

The design of Bonfiglioli asynchronous motors is engineered to operate even in difficult environmental conditions. The frames are made of die-cast aluminum for small sizes and cast iron for larger sizes, ensuring both lightness and rigidity.

FP Trasmissioni supports customers in configuring the ideal motor by analyzing the temperature, altitude, and humidity conditions of the installation site to provide the most suitable IP protection rating.

Design advantages include:

1. Wiring Flexibility: Adjustable terminal box to facilitate electrical connection in tight spaces.

2. Braking System: Possibility to integrate DC or AC brakes for precise and safe stops.

3. Dynamic Balancing: Precisely balanced rotors to minimize vibration and mechanical noise.

Ideal Applications for Asynchronous Motors

Bonfiglioli three-phase asynchronous motors are considered the number 1 solution for powering a vast range of industrial machinery.

Primary applications include:

• Factory Automation: Driving conveyor belts, palletizers, and assembly lines.

• Water Treatment: Powering pumps and aeration systems.

• Mechanical Industry: Control of machine tools and lifting systems.

• Ventilation: Driving large industrial fans and smoke extraction systems.

The adoption of this valuable technology ensures uncompromising reliability, reducing the risks of production downtime and improving the company’s environmental impact.
