    3/A Series

    The Bonfiglioli 3/A Series combines the high torque density of planetary gear units with the robustness and high speed of helical bevel products. This configuration provides great power transmission in a very compact space, thanks also to its angular layout. The 3/A Series is available for the lower range of the 300M Series and represents a smart path to medium-duty power transmission for the industrial market. The 3/A Series can be completed by selecting from of a wide range of electric motors entirely manufactured by Bonfiglioli. Asynchronous motors both IEC and compact (BN-BE-BX/M-ME-MX) and reluctance motors (BSR) can be coupled with the 3/A Series. With its broad e-motor portfolio, Bonfiglioli can always provide customers an outstandingly balanced solution in terms of efficiency, dynamics and cost-effectiveness.

    300M Series

    Bonfiglioli's 300M Series is an outstanding solution for all heavy-duty applications where compactness is not an option. Thanks to its modular design, the 300M Series can be customized to match an extremely wide range of applications. Bonfiglioli's expertise in planetary technology ensures high-quality product design and manufacturing procedures. The 300 Series operates without unwanted downtime even in the harshest environments. This planetary gearbox achieves top-class flexibility thanks to several outputs, as well as input configurations available for all 20 sizes. The 300M Series can be completed with a wide range of electric motors entirely manufactured by Bonfiglioli. Asynchronous motors (BN-BE-BX/M-ME-MX) can be coupled with 300M Series gearboxes, providing our customers a complete solution.

    A Series

    The A Series combines high efficiency and reliability, low maintenance costs and a wide torque range. The right angle layout between INPUT and OUTPUT makes the A Series particularly compact. The gear set combination makes this right-angle product the most efficient and durable in Bonfiglioli's light- and medium-duty portfolio. The A Series can be completed with a wide range of electric motors entirely manufactured by Bonfiglioli. Asynchronous motors both IEC and compact (BN-BE-BX/M-ME-MX), servomotors (BMD) and reluctance motors (BSR) can be coupled with the A Series.

    BE Series

    BX, BE and BN Series asynchronous motors with aluminum frames are the right solution for a wide range of general purpose industrial applications. Both the IEC and Compact motor are available in IE1 (BN/M) IE2 (BE/ME) and IE3 (BX/MX) efficiency classes according to the international standard IEC 60034-30. Furthermore, Bonfiglioli's e-motors can be equipped with several options: protection class up to IP 56, tropicalized, corrosion-resistant paint, and anti-condensation heaters. Moreover, the BN/M and BX/MX motor Series are also available in the BrakeMotor version with a selection of AC or DC brakes. To maximize our e-motor flexibility, all of them can be controlled with inverters.
