Abstract
Methods for evaluating lifetime expectations are discussed. Factors that affect the life of bearings and brushes and of wire coil insulation are identified. Thermal life of insulation and methods for accelerated testing are discussed. Examples are included to assist in the calculation of such factors as motor temperature-rise conditions and the benefits to be realized through upgrading the thermal classification of the motor insulation system.<>
