The motor manufacturers explored design and technology options available to achieve the optimum energy savings while maintaining what the Department of Energy (DOE) refers to as “product utility.” The outcome of the evaluation was to increase the required nominal efficiency levels of the new motor rule to Premium Efficiency (Table 12-12) levels. The members of the section concluded that by moving virtually all polyphase motors to this level, a change could be achieved within two years of enactment of the federal energy code (CFR10, part 431).
