Eficiencia energética de motores eléctricos de corriente alterna, trifásicos, de inducción, tipo jaula de ardilla, en potencia nominal de 0,746 kW a 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).

For the process to certify Three-Phase AC Squirrel-Cage Induction Motors, group them into a family according to the following table and taking as a reference the full-load nominal efficiency values established in the same table, which considers enclosed, open, horizontal and vertical motors.

FAMILY GROUPING

MOUNTING POSITION FOR OPERATION FAMILY TYPE OF ENCLOSURE kW (CP) NO. OF POLES NUMBER OF MOTORS IN THE SAMPLE.
HORIZONTAL OR VERTICAL 1 OPEN 0.746 (1.0) to 14.920 (20) 2, 4, 6, 8 2 MOTORS

GIVING PRIORITY TO THE SELECTION OF A MODEL OTHER THAN THE PREVIOUS CERTIFICATION MODEL

HORIZONTAL OR VERTICAL 2 OPEN 14.921 (20.1) to 74.60 (100.0) 2, 4, 6, 8 2 MOTORS

GIVING PRIORITY TO THE SELECTION OF A MODEL OTHER THAN THE PREVIOUS CERTIFICATION MODEL

HORIZONTAL OR VERTICAL 3 OPEN 74.61 (100.1) to 373 (500) 2, 4, 6, 8 1 MOTOR

GIVING PRIORITY TO THE SELECTION OF A MODEL OTHER THAN THE PREVIOUS CERTIFICATION MODEL

HORIZONTAL OR VERTICAL 4 ENCLOSED 0,746 (1.0) to 14.920 (20) 2, 4, 6, 8 2 MOTORS

GIVING PRIORITY TO THE SELECTION OF A MODEL OTHER THAN THE PREVIOUS CERTIFICATION MODEL

HORIZONTAL OR VERTICAL 5 ENCLOSED 14.921 (20.1) to 74.60 (100.0) 2, 4, 6, 8 2 MOTORS

GIVING PRIORITY TO THE SELECTION OF A MODEL OTHER THAN THE PREVIOUS CERTIFICATION MODEL

HORIZONTAL OR VERTICAL 6 ENCLOSED 74.61 (100.1) to 373 (500) 2, 4, 6, 8 1 MOTOR

GIVING PRIORITY TO THE SELECTION OF A MODEL OTHER THAN THE PREVIOUS CERTIFICATION MODEL.

NOTES:

1)     FOR THOSE PRODUCT FAMILIES REQUIRING A CERTIFICATION FOR MOTORS IN BOTH MOUNTING POSITIONS (HORIONTAL AND VERTICAL), SEND FOR LABORATORY TESTIG THE SAMPLES FOR EACH TYPE OF MOTOR.

2)     IN THE CASE OF THOSE PRODUCT FAMILIES REQUIRING ONLY A CERTIFICATION FOR MOTORS IN 1 MOUNTING POSITION (HORIZONTAL OR VERTICAL), SEND FOR LABORATORY TESTING ONLY THE SAMPLE CORRESPONDING TO THE TYPE OF MOTOR REQUIRED TO BE CERTIFIED.

3)     FOR PRODUCT FAMILIES THAT ALREADY HAVE A CERTIFICATE FOR MOTORS IN A GIVEN MOUNTING POSITION, AND IN THE CASE OF REQUIRING TO ‘EXTEND THE CERTIFICATE’ FOR MOTORS IN ANOTHER POSITION, SUBMIT THE CORRESPONDING TEST REPORT, AS REQUIRED FOR THE PRODUCT FAMILY.

4)     ONLY ONE SAMPLE OF A MOTOR IS REQUIRED FOR PRODUCT FAMILIES 3 AND 6. IT MAY BE HORIZONTAL OR VERTICAL.
