Abstract
Standard information available for motors includes the horsepower, current, speed, power factor, and efficiency at discrete points. Torque at strategic points is also available. It is shown how the data points can be used to determine speed variation and efficiency for a motor. Determination of the most efficient induction motor for a given load is discussed. Ultrahigh slip motors as well as National Electrical Manufacturers´ Association design motors are evaluated. A comparison of operating costs and investment is presented.<>
