Abstract :
This paper reviews the motor temperature operating consideration for totally enclosed fan cooled (TEFC), open dripproof and weather protected II type of motor through 500 hp, both low voltage (LV) and medium voltage (MV). The IEEE Standard 841 has been revised as IEEE Std 841-2001 and is expected to be in use for at least five years. The TEFC motors covered in this standard have found wide acceptance in the pulp and paper industry. Much of the material also applies to large motors sizes. The thermal impact on the stator winding rotor core, bearings, and lubrications as specified in standards and applied in mills are considered.
