Bonfiglioli BE 80B 4 Motor with C122PP80 Gearbox

Product Overview

The Bonfiglioli BE 80B 4 is an industrial electric motor rated at 0.75 kW, combined with a C122PP80 gearbox in this drive arrangement. The motor provides input power, and the gearbox reduces speed and increases torque for the driven machine. The unit is used where a compact motor and gearbox assembly simplifies installation and alignment.

The gearmotor is suitable for conveyors, packaging equipment, material handling, and general industrial machinery. Correct selection depends on output torque, speed, duty cycle, mounting position, and environment. The unit should be installed by qualified personnel and according to technical documentation.

Construction and Mechanical Design

The motor uses a robust industrial construction with a frame that supports the stator, rotor, bearings, and shaft. The gearbox contains a housing, gear stages, bearings, and sealing elements. The gear stages reduce speed and increase torque. Seals retain lubricant and reduce the entry of dust and moisture. The mounting interface and output shaft must match the machine structure.

Installation requires a clean, flat, and rigid mounting surface. The unit should seat without distortion. Fasteners must be tightened to the specified torque and checked after initial operation. Shaft connections should be aligned carefully. Excessive overhung load or belt tension can affect bearing life.

Electrical Connection and Commissioning

The motor nameplate provides voltage, current, frequency, power, speed, and connection details. The supply and control system must match these values. Star or delta connection must be correct for the available voltage. Protective earth must be connected. The terminal box wiring should be secure and protected from strain. Cable glands should maintain the enclosure protection.

If the motor is controlled by an inverter, the drive settings should match the motor data. Cable length and shielding should be considered. The direction of rotation should be checked before coupling to the load. Commissioning should include a no load run where possible. Current, noise, vibration, and temperature should be checked.

Lubrication and Thermal Conditions

Lubrication reduces friction and wear in the gear mesh and bearings. The specified lubricant type and quantity must be used. The mounting position determines the correct oil level and plug arrangement. Fill, level, and drain points should remain accessible.

Operating temperature should remain within the intended range. The motor frame and gear housing should have adequate air flow. Excessive temperature can indicate overload, incorrect lubricant, or inadequate cooling. Leakage should be corrected because low lubricant level can damage gears and bearings.

Operation and Monitoring

During operation, the gearmotor should run smoothly within the designed speed and torque range. Operators should monitor current, temperature, noise, vibration, and leakage. Excessive current can indicate overload or mechanical binding. Abnormal noise can indicate bearing wear or gear problems.

Load changes can affect gearmotor life. Increased throughput, higher torque, frequent starting, or shock loading should be reviewed against the original selection. The unit should not be operated beyond its rated conditions. Protective devices should remain active.

Protection and Reliability

Reliability depends on correct electrical protection, alignment, lubrication, and protection from contamination. Overload protection should be set according to the motor current. The unit should be protected from water, dust, and corrosive atmosphere beyond its rating.

If a fault occurs, the cause should be identified before restart. Repeated overload trips indicate a problem that should be corrected. Service work should be performed by qualified personnel. Opening the unit can affect bearings and seals.

Maintenance and Service

Maintenance should include periodic inspection of lubricant, seals, fasteners, terminals, cooling, and running conditions. The interval depends on operating hours, load, temperature, and environment. Dust and dirt should be removed from the motor frame and gear housing.

Before service, the machine must be isolated and secured against rotation. Cables should be labeled before disconnection. After service, alignment, electrical connections, and lubricant level should be checked. The unit should be run briefly before return to full duty.

Integration and Selection Summary

The BE 80B 4 motor with C122PP80 gearbox can be integrated into industrial machines that require a compact gearmotor arrangement. The final application determines protection, mounting position, control method, and maintenance access.

Selection should confirm the motor model BE 80B 4, 0.75 kW rating, C122PP80 gearbox, ratio, torque capacity, mounting position, and lubrication requirements. The designer should verify compatibility with the supply and driven machine. Documentation should be reviewed before installation.
