The equation for power is P Wt P stands for power in watts W stands for the amount of work done in Joules or energy expended in Joules t stands for the amount of time in seconds.

Though horsepower units is a derivative of the 33000 ft-lbf min it is not critical to understanding how to calculate motor horsepower for speed and torque. Work Energy and Power W Fdcosθ or W Fd W work F force d distance θ anglebetweenF and the direction of motion F. Electric power is commonly supplied by sources such as electric batteries and produced by electric generators.
