Power Index Calculation Procedure—Standard Rating Methodology for Power Drive Systems and Complete Drive Modules

Standard Details

Owner: Leibowitz, Mike Product Areas: Motor & Generator Divisions: IS - Industrial Products & Systems ESPG Category: Motors & Generators 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.
