Eficiencia energética de motores eléctricos de corriente alterna, trifásicos, de inducción, tipo jaula de ardilla, en potencia nominal de 0,746 kW a 0,373 kW. Límites, métodos de prueba y marcado (Energy Efficiency for Three-Phase Alternating-Current Squirrel-Cage Induction Electric Motors rated 0.746 to 373 kW. Limits, Testing Methods, and Marking).

This Norma Oficial Mexicana (‘NOM,’ Official Mexican Standard in English) sets forth nominal efficiency values, testing method for assessing these values, acceptance criteria, and specifications for the minimum information to be marked on the nameplate for Three-Phase Alternating-Current Squirrel-Cage Induction Open and Enclosed Electric Motors rated 0.746 to 373 kW, which are marketed in Mexico. In addition to responding to the needs to promote energy saving, this NOM also allows a contribution to preserve the country’s non-renewable natural resources.

This NOM applies to Continuous-Duty, Air-Cooled, Horizontally or Vertically Mounted, Single Rotational Frequency (rotational speed of the motor shaft or axis), Open or Enclosed, Three-Phase Squirrel-Cage AC Induction Electric Motors with a rated output of 0.746 to 373 kW and rated voltage up to 600 V, which are marketed in the country.
