Product Description

.1. PRODUCT INTRODUCTION OF NEMA PREMIUM ELECTRIC MOTOR

NEMA Premium series are 3 phase asynchronous motors with totally enclosed fan cooled, are ac motors ,INDUCTION MOTORs and industrial motors. The premium efficiency motors are developed by ourselves independently according to NEMA Premium Efficiency of NEMA EPACT. The output rated power and mounting dimensions of the motors are perfectly in accordance with NEMA. NEMA premium motors is reasonable structure, small vibration and low noise.

NEMA Premium series 3 phase asynchronous motors can be widely used in blowers, ventilators, pumps, machine tools, compressor, reducers, packing machines, transportation machinery, mining equipment, construction equipment and other machines which can operate with full load for a long time, the electrical motors can save the considerable electric energy, it is advantageous to protect the environment.
