Energy efficient motors (EE motors) are discussed and compared to standard electric motors. Pitfalls and warnings are provided for the novice prospective purchaser. The best comparison between the two types of electric motors is cited to be a direct comparison of the EE motor with published statistics of the average of all known standard motors. It is shown that efficiency of both types of motors increases as the horsepower of the motor increases. The economics of EE motors are discussed with emphasis on the initial cost and cost of operation. Payback periods as a function of horsepower are discussed and illustrated. In most cases, electricity savings exceed the premium initial cost within the first year of operation. For a 200 horsepower motor, the payback period is 4 months even though the EE motor is only 1.2% more efficient. (MJJ)
