rotor inertia of AC 3 phase motor
rotor inertia of AC 3 phase motor
(OP)
Hello,
Can anyone provide an estimated rotor inertia for a 25 hp, 1750 rpm, 575 volt, 284T frame, severe duty AC motor?
Thank you

RE: rotor inertia of AC 3 phase motor
WK2=0.02*2^(poles/2)*hp^(1.35-0.05*poles/2)
where
HP in HP. WK^2 in ft^2-pounds
For this motor (poles-4, HP=25), we calculate
WK2 = 0.02*2^(4/2)*25^(1.35-0.05*4/2)
WK2 = 4.47 FT^2*lb
Same as above
