FAQ

Question?

Can this motor be run with a variable frequency drive (VFD)?

Answer

Yes, the Bonfiglioli BN 63A 4 is a standard three-phase induction motor suitable for VFD operation. Ensure the VFD is configured for the motor’s voltage (230V or 400V) and current ratings, and maintain proper cooling, especially at low speeds.

Question?

What type of oil is required for the S.T.M. UMI 40 gearbox and what is the mounting position?

Answer

The S.T.M. UMI series is typically filled with synthetic oil (ISO VG 320) for life. The label indicates mounting position ‘M1’, which is a standard universal position for this gearbox size, allowing for flexible installation without changing the oil level.

Question?

The motor is from Bonfiglioli and the gearbox from S.T.M. Are they compatible?

Answer

Yes, this assembly is fully compatible. The motor features a standard IEC B14 flange and shaft dimensions that match the input of the S.T.M. UMI 40 gearbox. This combination of components from different manufacturers is common in industrial applications.
