sphere’s standard for measuring the rate at which motors and other drives can produce work. For example, a 1 H.P. motor can produce 33,000 ft. lbs. of work in one minute. Torque and horsepower are related to each other by a basic formula which states that: Horsepower = Torque Speed Constant The value of the constant changes depending upon the
