GE EnergyPower Conversion1.INTRODUCTIONAn effective motor maintenance program is a preventive and corrective maintenance schedule that beginswith reviewing a motor’s service history. This review may reveal on-going problems that are both integral tothe motor itself as well as external conditions (e.g., overloads, unbalances, misapplications) that are adverselyaffecting the motor’s normal operating condition. Once regular maintenance checks are incorporated into ashop’s work schedule, they soon become transparent yet will secure cost-savings well beyond the investmentin time and materials spent in maintaining them.The maintenance concept is aimed at reducing the probability of failure or damage to the motor underintensive use and under the environmental operating conditions at the site.The various preventive maintenance actions must therefore be programmed to ensure:- the operational availability of the motor in accordance with the functional requirements, at optimum costefficiency,- the operational safety of the motor, personnel and environment in observance of the applicableregulations,- the forecast service life of the asynchronous machines.Failure prevention must therefore be covered by a preventive maintenance task schedule defined inaccordance with the various functionalities of the motor components and predefined criteria relative to theirstate of deterioration.This section gives general recom
