My Content
1 May 2009
I am starting out on a project to look at possible savings from replacing some oversized motors.


Motor Input kW has been calculated from:
kW=(Volts x Amps x 1.73 x P.F.)/1000

Motor Load has been calculated from:
Load=kW/(Rated HP x 0.746)

All values are measured.If I have a 10 H.P. motor running at 50% load, how do I justify replacing it with a 5 H.P. motor.
