Changing blower/pulley speed
Changing blower/pulley speed
(OP)
I need help finding the formula and using the formula correctly to change speed on a electric motor / v-belt driven blower. The blower pulley is a 3v3.65 3sh turning 3400rpm and the motor pulley is a 3v6.9 3sds turning 1750 rpm.
I need the blower to be turning 2750 rpm. How do I figure this out? I am not an engineer and any help would be appreciated.

------------------------------ = RPM
Dia. of driven
I just kept changing the Dia. of driven until the RPM = 2400.
1750 x 6.9
---------- = 2415rpm
5.0
Does this look right?
