Combined Planetary/Helical Bevel Gearmotors & Units

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 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 with an outstandingly balanced solution in terms of efficiency, dynamics, and cost-effectiveness.
