    I have a universal motor running that has given me : torque,current, voltage, watts and rpm's. What formula can I use to get horsepower? I've tried HP = 2(3.14)(S)(T)divided by 33000 is this correct when T= torque and S = speed

    Get the power by multiplying torque by the speed and then convert to horsepower. Note that the torque must be measured in Nm and the speed in rad/s.
