Abstract:
With increasing energy costs and renewed focus on using energy in ways that support the environment,
a structured approach is required to ensure that energy is used efficiently. A comprehensive
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 presented
incorporates benefits that can be obtained from using in-situ motor efficiency estimation
and condition monitoring techniques as part of a motor management system.
