Evaluation of energy performance of motor system
1 Scope
This document specifies the evaluation grades and procedures of energy performance of motor system.
This document is applicable to the evaluation of energy performance of stably operating motor system (hereinafter referred to as the "system") composed of small and medium-sized motors (below 1000kW), single drag equipment (fan, pump, air compressor) and its control device, transmission device and pipe network. It also can be used as an inference by other complex motor systems, motor system station buildings, etc.
