3 V Series

3/V Series

Combined Planetary/Worm Gearmotors & Units

Thanks to more than 60 years of experience in worm and planetary technologies, the Bonfiglioli 3/V Series offer our customers the highest performance and reliability: the high torque density of the planetary gear units with the high gear ratio and cost-effectiveness characterizing worm technology. The result a solution which is ideal for intermittent duty applications, characterized by elevated reliability and highly customizable thanks to its great modularity. Finally, our 3/V 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/V Series. With its broad e-motor portfolio, Bonfiglioli can always provide customers an outstandingly balanced solution in terms of efficiency, dynamics and cost effectiveness.
