# Induction Motor Slip decrease with frequency decrease for same load.

Hi,

Does anyone know or could help me understand the reasoning for the amount of slip within an induction motor decreasing with frequency under the same load conditions? I.e. For no external load, the slip is higher at 50Hz than at 20Hz etc? Thanks

Is windage proportional to speed2 or to speed3 ?

$P=T\omega=2\pi_fT$
