Bonfiglioli 0.12 kW Gear Motor BN 63 B6 with BN63B6 Gearbox
The Bonfiglioli 0.12 kW gear motor BN 63 B6 with BN63B6 gearbox is a low power integrated drive unit that combines a frame 63 three phase motor with a matched reducer. The BN 63 B6 designation identifies a six pole motor on the frame 63 size, and the gearbox reduces the motor speed to an output of approximately 12 revolutions per minute. This very low output speed makes the unit suitable for small conveyors, rotary feeders, and other machinery that requires slow, steady rotation with high torque multiplication.
Product Overview
The BN series is a well established range of Bonfiglioli three phase motors used in industrial drive systems. The frame 63 size is compact and fits machines with limited mounting space. The six pole configuration produces a lower motor speed and higher torque compared with four pole motors of the same frame size. The 0.12 kW rating places the motor in the low power range, which is common for auxiliary drives and small equipment.
The gearbox reduces the motor speed to approximately 12 revolutions per minute at the output shaft. This level of reduction is achieved through a matched gear stage that multiplies the motor torque. The integrated assembly simplifies installation because the motor and gearbox are aligned at assembly. The unit is intended for machines that need slow, controlled movement rather than high speed rotation.
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 loads. The fan and fan cover provide cooling airflow over the motor housing. The terminal box provides a safe connection point for the electrical supply.
The gearbox housing supports the gear stages and bearings with sufficient rigidity for stable mesh. Lubrication is contained within the housing and distributed to the gears and bearings during operation. Seals protect the internal components from dust and moisture. The output shaft is machined to accept couplings, pulleys, sprockets, or other driven components. The assembly should be handled carefully during installation to avoid damage to the output shaft and seals.
Performance Characteristics
The 0.12 kW motor provides low power input, while the gearbox converts the motor speed into a very low output speed with higher torque. The six pole motor design contributes to smooth running and reduced starting current compared with higher speed motors. The output speed of approximately 12 revolutions per minute is suitable for slow feeding, indexing, or conveying duties.
The gear motor should be selected with an appropriate service factor for the duty cycle. Starting loads, shock loads, and continuous operation affect the thermal and mechanical capacity of the assembly. The motor should be protected against overload and abnormal supply conditions. The gearbox should be checked for thermal capacity when operating at high duty cycles or in high ambient temperatures.
Applications
The Bonfiglioli BN63B6 gear motor is suitable for small conveyors, rotary feeders, packaging units, labeling equipment, and general industrial machinery. The very low output speed makes it useful in applications that require slow, steady movement. The compact frame 63 design allows the unit to fit into machines where space is limited.
The motor can be connected to standard industrial supplies according to its nameplate rating. The geared drive can be used in applications that require frequent starting and stopping, provided the duty cycle and thermal capacity are considered. Correct selection helps ensure reliable operation and long service life.
Installation Guidelines
Installation should begin with a check of the nameplate data and a visual inspection of the assembly. The geared motor should be mounted on a rigid base that can withstand the torque reaction. Mounting bolts should be tightened to the recommended torque. The motor should be wired according to the terminal diagram for the available supply voltage. The output shaft should be aligned with the driven equipment to avoid excessive radial and axial loads.
After installation, the assembly should be checked for smooth rotation and correct oil level in the gearbox. A short run without load helps confirm that the motor and gearbox operate correctly. The direction of rotation should be verified before connecting the load. Any unusual noise, vibration, or temperature rise should be investigated before full service.
Maintenance Recommendations
Regular maintenance supports reliable performance and long service life. The motor cooling fan and fan cover should be kept clean. The gearbox oil level and oil condition should be checked at recommended intervals. Seals and bearings should be inspected periodically. Leakage, abnormal noise, or vibration should be addressed promptly. Electrical connections should be checked for tightness and signs of overheating.
The exterior of the motor and gearbox should be kept clean to support heat dissipation. Adequate airflow around the assembly helps maintain stable temperatures. In dusty or humid environments, additional protection may be needed. Maintenance records help identify trends and support planned servicing. Following a consistent maintenance schedule reduces the risk of unexpected downtime.
Selection Considerations
When selecting the BN63B6 gear motor, engineers should confirm the supply voltage, frequency, motor power, output speed, output torque, duty cycle, and environmental conditions. The gearbox ratio and motor speed determine the output speed. The available torque depends on motor power and gearbox efficiency. A service factor should be applied for starting loads, shock loads, and continuous operation.
The motor and gearbox interfaces must match. The mounting arrangement should suit the machine layout and provide adequate support. The output shaft and mounting features should match the driven equipment. Correct selection and installation help ensure smooth operation, stable thermal behavior, and long service life.
Conclusion
The Bonfiglioli BN63B6 gear motor with a 0.12 kW motor and approximately 12 revolutions per minute output offers a low speed integrated drive solution. Its construction supports steady torque transmission in small conveyors, feeders, and industrial machinery. With correct installation and maintenance, the assembly provides stable performance and long service life.
