    NEMA MG 10011-2024 Power Index Calculation Procedure-Standard Rating Methodology for Power Drive Systems and Complete Drive Modules
    Edition: 2024

Content Description

This standard establishes the calculation procedure 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.

About NEMA

 NEMA is an abbreviation for National Electrical Manufacturers Association. It is a trade association representing manufacturers of electrical products and equipment.
