Motor Installed Power vs. Power Input

Can you repost the table as a larger picture, I can barely read it when magnified. All I can see is it looks like you are trying to compare a 0.25kW motor to a 30kW motor.

Thanks Mr. Jack

there are tow selection EXF=0.25 & SAF=30kw

I don't compare between them but i need to now why the installed power in exf lower than power input while in saf installed power greater than power input

It does look like a typo in the specification you have been given (where it says that the installed power is 30kW but the input power is 25kW). Based on the rated amps (A) of 54.7A at 400V/3ph/50Hz (which matches a standard 30kW 3ph motor) it looks like the power input (kW) should be 30kW, and the installed power should be 25kW.

Hope this clarifies the issue for you.

Which motor to choose? Well, the simple answer is to choose the one that is designed and sized properly for your application.

In actuality, I would choose magic motor #2. If you can get 30KW out of it by only putting in 25KW, I would go that route and start producing your own free energy.

I think there may be a typo on the specs.
