A Motor Management Strategy for Optimising Energy Use and Reducing Life Cycle Costs

With increasing energy costs and renewed focus on using energy in ways that support the envi-ronment, a structured approach is required to ensure that energy is used efficiently. A compre-hensive motor management strategy to reduce motor life cycle costs while increasing reliability is presented. The application of energy management principles is combined with benefits that can be obtained from using energy-efficiency motors. An economic model for determining the optimal time a motor should be replaced with a higher efficiency motor is proposed. The strategy pre-sented incorporates benefits that can be obtained from using in-situ motor efficiency estimation and condition monitoring techniques as part of a motor management system
