Bonfiglioli C102PP71 13.4 Ratio Variable Speed Inline Gear Motor 0.26kW 3PH

The Bonfiglioli C102PP71 13.4 ratio variable speed inline gear motor is an integrated drive unit that combines a C series inline gearbox with a 0.26 kW three phase motor. The C102PP71 configuration includes a P71 motor interface and a 13.4:1 reduction ratio. The inline layout places the motor and output shaft on the same axis, which simplifies machine design. This gear motor is suitable for industrial machinery that requires compact reduction and adjustable speed operation.

Product Overview

The C series inline gearbox uses helical gears to provide smooth and efficient torque transmission. Helical gears engage gradually, which reduces noise and impact compared with some other gear types. The C102 size is a compact unit suitable for light to moderate torque requirements. The 13.4:1 ratio provides a moderate speed reduction, making the gear motor suitable for conveyors, packaging equipment, and general industrial drives.

The P71 motor interface connects the three phase motor to the gearbox. The motor is rated at 0.26 kW and is designed for three phase supply. Variable speed operation is achieved when the motor is paired with a suitable frequency inverter or other speed control device. The integrated design reduces the number of separate components and simplifies installation.

Construction and Design

The helical gear stages are manufactured to precise tolerances to provide smooth rotation and low noise. The housing supports the shafts and bearings with high stiffness. 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 inline shaft arrangement allows the gear motor to be integrated into machines with a straight drive train.

The motor includes a stator, rotor, shaft, bearings, terminal box, and cooling provisions. The motor housing supports the internal components and provides mounting points. The P71 interface ensures proper alignment between the motor and gearbox. The output shaft is machined to accept couplings, pulleys, sprockets, or other driven components. Correct alignment between the gear motor and driven equipment is important for long bearing and seal life.

Performance Characteristics

The 13.4:1 ratio determines the output speed by dividing the motor speed by 13.4. The output torque depends on the motor power, gearbox efficiency, and service factor. The 0.26 kW motor provides low power input suitable for small machines and auxiliary drives. Helical gearing provides high efficiency and quiet operation. Variable speed control allows the output speed to be adjusted to match process requirements.

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 high ambient temperatures.

Applications

The Bonfiglioli C102PP71 gear motor is suitable for small conveyors, packaging machines, labeling equipment, assembly stations, and general industrial drives. The inline layout is useful in machines where the motor and driven shaft are arranged on the same axis. The 13.4:1 ratio provides a practical output speed for many light industrial applications.

The 0.26 kW motor is suitable for low power duties. Variable speed operation can be achieved with a compatible drive, allowing the machine to run at different rates. The gear motor can be used in applications that require frequent starting and stopping, provided that 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 gear motor. The unit should be mounted on a rigid base that can withstand the torque reaction. The output 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. Mounting bolts should be tightened to the recommended torque.

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. When a frequency inverter is used, the drive parameters should be set for the motor and application. After installation, a short run without load helps confirm correct operation.

Maintenance Recommendations

Regular maintenance supports reliable performance and long service life. Oil level and oil condition should be checked at recommended intervals. The first oil change should be performed after the initial running in period, and later changes should follow the schedule for the operating conditions. Seals and bearings should be inspected periodically. Leakage, abnormal noise, or vibration should be addressed promptly.

The motor cooling fan and fan cover should be kept clean. Electrical connections should be checked for tightness and signs of overheating. The exterior of the gear motor should be kept clean to support heat dissipation. In dusty or humid environments, additional protection may be needed. Following a consistent maintenance schedule reduces the risk of unexpected downtime.

Selection Considerations

When selecting the C102PP71 gear motor, engineers should confirm the required output torque, output speed, duty cycle, and environmental conditions. The 13.4:1 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 voltage and frequency should match the supply. The P71 interface and mounting arrangement should suit the machine design. When variable speed operation is required, the motor should be compatible with the selected drive. Correct selection and installation help ensure smooth operation, stable thermal behavior, and long service life.

Conclusion

The Bonfiglioli C102PP71 13.4 ratio variable speed inline gear motor offers a compact integrated drive solution with a 0.26 kW three phase motor and helical gear reduction. Its construction supports quiet operation and reliable torque transmission in small conveyors, packaging equipment, and industrial machinery. With correct installation and maintenance, the gear motor provides dependable performance and long service life.
