Horsepower Calculation
Horsepower Calculation
(OP)
Can someone confirm if this works to calculate horsepower for a motor?
I had some metering data provided on a 700hp motor. One of the measurements was kW and I was wondering if I can take this divide by 0.746 to get horsepower.
This would basically give the "electrical horsepower" then if I take machine efficieny into account this would give shaft mechanical horsepower.
i.e.
265kw measured
265/0.746 = 355.2hp what I called electrical horsepower above
355.2*.92 = 326.8hp shaft horsepower (assuming 92% efficient)
Thanks,

I guessed at 92 as it is an older motor. If 92 is a poor assumption for this older machine I can bump it up a little. If 97 works for older machines I will use that. I won't be able to get name plate data in time so have to make an assumption.
Cheers,
Jeff
