Brook Crompton New Motor Efficiency Standards – Effective June 1, 2016

This document outlines Brook Crompton’s adoption of updated motor efficiency standards effective June 1, 2016. It summarizes which motors are covered or excluded under the revised regulations and provides full-load efficiency values aligned with NEMA MG1-2014 Table 12-12 for premium-efficiency, random-wound electric motors rated 600 volts or less. This resource is intended to help engineers, maintenance professionals, and procurement teams ensure compliance and make informed motor selection decisions.

Key Points

  • Defines the scope of motors covered under the new efficiency standards, including horsepower range, voltage limits, duty type, and construction characteristics.
  • Clearly lists motor types not covered by the regulation, including single-phase, medium-voltage, servo, and inverter-only motors.
  • Aligns Brook Crompton motor offerings with U.S. DOE and NEMA MG1-2014 premium efficiency requirements.
  • Identifies motor types added to the existing NEMA MG1 Table 12-12 requirements, such as certain Design C, brake motors, and gearmotors.
  • Provides a detailed full-load efficiency table for 2-, 4-, 6-, and 8-pole premium-efficiency motors from 1 to 500 HP.
  • Serves as a quick compliance reference for specifying or replacing industrial electric motors after June 1, 2016.
