AS Series

The AS Series benefits from years of recognition in the industry and has become a best seller for quarry and mining applications, where reliability and low maintenance are key factors. These Series can be completed with a wide range of electric motors entirely manufactured by Bonfiglioli. Asynchronous motors both IEC and compact (BN-BE-BX) and reluctance motors (BSR) can be coupled with the AS Series: Thanks to the breadth of its e-motor portfolio, Bonfiglioli can always provide customers with the perfectly balanced solution, in terms of efficiency, dynamics and cost-effectiveness.
