With the continuing escalation of the cost of electrical energy, motor manufacturers and appliers are increasingly concerned with the energy conservation available from high efficiency electrical motors. The revised NEMA Standard on Motor Efficiency is described, as well as its use by motor manufacturers and users and the several years of work invested in preparing and validating the standard.
