NEMA MG 10011-2024 PDF

This standard establishes the calculation procedure for the Motor Coalition Metric. provides a means to compare the relative energy savings of motors (both fixed and variable speed) to a standard baseline motor. For polyphase equipment, this is a premium efficient direct-on-line motor (i.e., IE3 equivalent). This metric represents weighted-average power consumption relative to a fixed speed motor similar to NEMA’s Power Index.  This metric provides a rank ordering and a conservative estimate of energy savings relative to a single speed baseline product.
