Universal Worm Gearmotors & Units

VF/W Series are worldwide known: they succeeded in combining uncompromising quality with state-of-the-art technology and price effectiveness. Absolute flexibility is achieved by the wide choice of mounting options, shaft configurations and motor interfaces, all offered as standard. Furthermore, thanks to several patented manufacturing techniques Bonfiglioli's VF/W Series stands out for their long operating lifetime and reliability. Finally, our VF/W Series can be completed through the selection of a wide range of electric motor entirely manufactured by Bonfiglioli. Asynchronous-motors, both IEC and compact (BN-BE-BX/M-ME-MX), can be coupled with VF/W Series providing to our customers a complete drive solution. Looking for an Enhanced Protection Gearmotor suitable for Food&Beverage, Chemical and Pharma industries as well as for harsh environments in general?
