output power of a motor = 2*pi*(N/60)*T
N ----> Speed of the motor in RPM
T -----> Output or load torque..
T = 9.81*Weight of the Load*Radius of the load
(since torque = force * perpendicular dist)
of course, from the above equation, you will get the power in Watts to convert into HP multiply with appropriate factor,,, iam not sure sure but i think 4.7*watts = HP.. it maybe wrong.. check it..
