A fan motor input is 16kw at 800rpm. what will be its input power if its rpm reduced to 600.kindly clarify the answere with calculation.




It really depends on your fan's torque speed curve when the speed is reduced to 600RPM.

A motor is always the slave of the load and giving whatever the load requires within it's max possible capacity till it fails.


The input power will also be dependent on the driver which you are using to reduce the speed. i.e pulley, gearbox or VVVF?

Calculations will depend on what you are using and what you want to know.
