A Series.png



Helical Bevel Gearmotors & Units

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.
