please i need to know the windage coefficient of 90KW 1500rpm induction motor. please i need this value for modelling my system. can anyone help me to obtain this value? thx.

 

Responding to "d's" query.

Here's a start. As part of earlier study related to motor efficiency vs size, the windage & friction power loss for the motor in question is about 2.4%.

Please could you give me the windage and friction power loss for a 7.5W and 1500RPM induction motor? Thank you.
