Bonfiglioli 4APC3-4 9142882 Geared Motor 380/220V 0.18KW 1350 rpm

The Bonfiglioli 4APC3-4 9142882 geared motor is a compact drive unit that integrates a three phase electric motor with a matched gear reducer. With a rated power of 0.18 kW and an operating speed of approximately 1350 revolutions per minute, this unit is designed for light industrial applications that require reliable torque delivery in a small package. The dual voltage designation of 380/220V allows the motor to be connected to different supply configurations, adding flexibility to system design and installation.

Product Overview

The 4APC3-4 geared motor belongs to the family of Bonfiglioli drive solutions that combine proven motor technology with precision gear reduction. The 0.18 kW rating places it in the low power range, making it suitable for applications where compact size and energy efficiency are important. The motor operates at approximately 1350 rpm, which is typical for a four pole machine under load, and the integrated reducer further reduces the output speed to match the requirements of the driven equipment.

The complete assembly is engineered for straightforward installation and dependable continuous operation. The motor and gearbox are factory matched to ensure proper alignment, efficient power transmission, and minimal vibration. This integrated approach reduces the number of components that must be sourced and assembled by the end user.

Performance and Efficiency

The 0.18 kW motor is designed to deliver steady torque with low power consumption, which makes it well suited to small machines and auxiliary drives. The three phase design provides smoother operation than single phase alternatives and is generally more efficient over long operating periods. The 1350 rpm speed is close to the synchronous speed of a four pole motor minus slip, indicating that the motor is operating in its normal range.

The integrated gear reducer multiplies the motor torque and reduces the output speed to a level that matches the driven equipment. This combination allows the unit to handle loads that would be difficult for a direct drive motor of the same power. The factory matched assembly also ensures that the gearbox efficiency is preserved because the alignment between motor shaft and gearbox input is set during manufacturing.

Applications

The Bonfiglioli 4APC3-4 9142882 geared motor is suitable for a wide range of light industrial applications. Common uses include small belt conveyors, packaging machinery, labeling equipment, assembly stations, rotary tables, and automated handling systems. Its compact size and low power rating make it especially appropriate for equipment where space is limited and precise motion control is required.

The dual voltage capability of 380/220V allows the motor to be used in different electrical environments. This flexibility is useful for equipment manufacturers that supply machinery to multiple regions or for facilities that operate with different voltage levels. The geared motor can be paired with standard control devices such as contactors, overload relays, and variable frequency drives when speed adjustment is needed.

Installation Guidelines

Installation should begin with careful inspection of the unit and verification that the nameplate data matches the intended application. The motor should be mounted on a rigid base that can withstand the torque reaction during operation. Alignment between the gearbox output and the driven shaft must be checked to prevent excessive radial loads and premature bearing wear. Couplings should be fitted according to the manufacturer recommendations.

Electrical connections should be made by qualified personnel following local codes and regulations. The motor terminal box should be wired for the appropriate supply voltage, and the direction of rotation should be verified before coupling to the load. Proper grounding is essential for safe operation. After installation, a short test run without load helps confirm that the unit operates smoothly and without unusual noise.

Maintenance Recommendations

The geared motor requires regular inspection to maintain reliable performance. The motor cooling fan and fan cover should be kept clean to ensure adequate airflow. The gearbox oil level should be checked periodically, and oil should be changed according to the recommended schedule based on operating hours and conditions. Bearing noise and vibration should be monitored, and any abnormal signs should be investigated promptly.

Electrical connections should be checked for tightness and signs of overheating. The motor insulation resistance can be measured periodically to detect deterioration. In environments with dust or moisture, additional protection measures may be needed to preserve the service life of the motor and gearbox. Following a consistent maintenance schedule helps avoid unexpected downtime and extends the operating life of the unit.

Selection Considerations

When selecting the 4APC3-4 9142882 geared motor, engineers should confirm that the output torque and speed match the requirements of the driven equipment. The reduction ratio of the integrated gearbox determines the final output speed, and the available torque must include an appropriate service factor for the application. The 380/220V voltage rating should match the available power supply, and the control method should be chosen based on whether fixed speed or variable speed operation is needed.

The compact design of this geared motor makes it easy to integrate into new and existing machines. Its low power rating is suitable for auxiliary functions rather than heavy duty primary drives. For applications with high starting torque or frequent reversing, the motor and gearbox should be sized with additional margin to ensure reliable long term operation.

Conclusion

The Bonfiglioli 4APC3-4 9142882 geared motor offers a compact and efficient drive solution with 0.18 kW of power, 380/220V dual voltage compatibility, and an operating speed of approximately 1350 rpm. Its integrated gear reducer, matched assembly, and three phase motor design make it suitable for conveyors, packaging machinery, and automation equipment. With proper installation and maintenance, this geared motor provides dependable performance and long service life.
