what is the Agitator RPM when we used 1450 rpm motor

1 comments:
Mr. Anderson

The agitator RPM depends on the gear ratio of the BONFIGLIOLI AS Series gearbox. The output speed (agitator RPM) is calculated as:

Agitator RPM = Motor RPM / Gear Ratio

From the provided document, typical gear ratios are listed in the data tables. For example, if the gear ratio is 14, then:

Agitator RPM = 1450 / 14 ≈ 103.6 RPM

If a different gear ratio is used, the agitator RPM will vary accordingly.
