BONFIGLIOLI BE 160 L 4 400/690 - 50 IP55 CLF B5 U1 15 kW Motor
The BONFIGLIOLI BE 160 L 4 motor is a three phase electric motor built on the IEC 160 frame with a four pole configuration. It is rated at 15 kW and designed for 400/690V 50Hz supply with IP55 protection. The CLF and B5 designations define the motor configuration and flange mounting arrangement, and U1 identifies a specific option or build detail. This motor is suitable for pumps, fans, compressors, and general industrial machinery that require medium power and reliable continuous operation.
Product Overview
The BE series is part of the Bonfiglioli range of three phase motors used in industrial drive systems. The frame 160 size is a medium frame that provides a balance between power capacity and physical dimensions. The four pole configuration produces a moderate speed suitable for many general applications. The 15 kW rating places the motor in the medium power range, which is common for pumps, fans, and process equipment.
The 400/690V rating allows the motor to be connected to different supply arrangements according to the terminal connection. The IP55 protection degree indicates resistance to dust and water jets in normal industrial environments. The B5 flange provides a standard mounting interface for direct connection to a gearbox or machine flange.
Construction and Design
The motor housing supports the stator, rotor, bearings, and shaft. The stator windings are insulated for industrial operation. The rotor is mounted on a shaft supported by bearings selected for the expected radial and axial loads. The fan and fan cover provide cooling airflow over the housing. The terminal box provides a safe connection point for the electrical supply.
The B5 flange is machined for precise mounting. The shaft extension is machined to accept couplings, pulleys, or other driven components. The IP55 enclosure protects the internal components from dust and water jets. Correct alignment with the driven equipment is important for long bearing and seal life.
Performance Characteristics
The BE 160 L 4 motor provides 15 kW of output power at a moderate four pole speed. The motor is designed for continuous industrial duty when operated within its rated voltage, frequency, and ambient conditions. Starting current and starting torque should be considered when selecting protective devices and control equipment.
The motor should be protected against overload, phase loss, and abnormal supply conditions. Efficiency and thermal behavior are important in continuous operation. Adequate ventilation around the motor helps maintain stable temperatures. When variable speed operation is required, the motor and drive should be selected together to ensure compatibility.
Applications
The Bonfiglioli BE 160 L 4 motor is suitable for pumps, fans, compressors, conveyors, mixers, and general industrial machinery. The 15 kW rating provides enough power for medium duty applications. The B5 flange mounting is useful when the motor must be mounted directly to a gearbox or machine flange.
The operating environment should be considered when applying the motor. Dust, moisture, chemicals, and high ambient temperatures can affect insulation, bearings, and cooling. The IP55 protection suits many normal industrial environments, but additional protection may be needed in harsh conditions.
Installation Guidelines
Installation should begin with a check of the nameplate data and a visual inspection of the motor. The motor should be mounted using the B5 flange on a mating surface that provides adequate support. The shaft should be aligned with the driven equipment to avoid excessive radial and axial loads. Couplings should be fitted according to the manufacturer recommendations and checked for alignment.
Electrical connections should be made by qualified personnel following local regulations. The supply voltage and frequency must match the motor rating. The direction of rotation should be verified before connecting the load. Proper grounding is essential for safe operation. After installation, a short run without load helps confirm correct operation.
Maintenance Recommendations
Regular maintenance helps ensure reliable motor operation. The cooling fan and fan cover should be kept clean to maintain airflow. Bearing noise and vibration should be monitored. The motor insulation resistance can be measured periodically to detect deterioration. Electrical connections should be checked for tightness and signs of overheating.
In environments with dust or moisture, additional protection measures may be needed. The motor should be kept clean and dry. Maintenance records help identify trends and support planned servicing.
Selection Considerations
When selecting the BE 160 L 4 motor, engineers should confirm the supply voltage, frequency, phase, rated power, speed, frame size, mounting, and enclosure requirements. The motor must provide enough torque for the load under starting and running conditions. The duty cycle and ambient temperature affect thermal capacity.
The motor interface must match the driven equipment or gearbox. Shaft dimensions, flange dimensions, and mounting holes should be checked. For variable speed applications, the motor should be compatible with the selected drive.
Conclusion
The BONFIGLIOLI BE 160 L 4 400/690 - 50 IP55 CLF B5 U1 15 kW motor offers a medium power three phase drive solution with IP55 protection and flange mounting. Its construction supports reliable operation in pumps, fans, compressors, and industrial machinery. With correct installation and maintenance, the motor provides stable performance and long service life.
