Answer / abdul hameed

there is no relationship between speed and hp but we can calculate the hp from the current for each phase

Answer / shaju

As we know,
we can calcualte torque by equation,

Torque=(1800/RPM)*HP*3
From this we can calculate HP from Speed.
i.e HP=(Torque*RPM)/(1800*3)
or HP=(Torque*RPM)/(5400)

Answer / bhatt

Power = 2 * pi * Speed *Torque/4500 Watt
Power in HP = Power in watt/746
