Motor Capacity Vs Load
Motor Capacity Vs Load
(OP)
Dear All
I am using 18 KW induction motor which draws 18 amps. at its load. What are the savings that I can gain if I used 11KW motor to run the same load.
Thank you
Sahan

This may not be true for all motors, but some it is.
So if you are under loading your motor, are you having power factor problems also?

Check out your current motor eff. If it is not a newer motor most likely you can save on operating expense by buying a high eff motor.
Of course you want your load to match the most eff curve of the motor.
I tell my operations elec guys to replace any older low effiecent motors (< 20 hp or so) with new higher eff ones, even if they are still working fine.
The size of the motor doesn't greatly effect the power draw. It is motor load determined, as long as they are approx the same size or motor.
By comparing eff you should be able to easily calculate the operational cost savings between two eff ratings.
