what is relation of rpm with Power supply? rpm directly Proposational to power ?..

freq is directly proportional to speed.and active power is
directly prop to freq.thus rpm depends on active supply
and.jus like at low volt the fan draws more current at a
greater slip and lower pf to prod rated speed which is
undesriable..rpm is dircetly prop to power.

mechanical o/p=(2*3.14*n*t)/60 ,mechanical i/p of a generator = electrical o/p (if loss is negligible), then (2*3.14*n*t)/60=v*i (concider o/p is dc ),speed(n) increases mec o/p increases there fore generator i/p also increases,o/p of generator is v*i (emf=n*(d pi/dt),emf=v) due to increase in speed the voltage also increases there electrical o/p also increases
