Abstract :
This paper reviews the operating temperature considerations and performance characteristics for totally enclosed fan-cooled motors as covered in the IEEE 841-2000 motor standard. NEMA MG-1-1998 motor standards are also included since they are embodied in the IEEE standard. Although the scope of product covered is for AC squirrel-cage induction motors through 500 hp, the material presented has application with many other sizes and types of motor. The paper reviews this standard as it applies to the motor operating temperature and various performance characteristics. The impact of temperature on the stator winding, rotor cage, bearings, lubrications, as well as the effects on motor efficiency and other applicable life factors, are considered
