Defining Motor System Management
In 1993, I had originally defined electric motor system maintenance and management as Total Motor System Maintenance and Management. Following that period, other motor management definitions were put forward focusing on: Energy efficiency; Repair vs replace decisions; Maintenance and Predictive Maintenance; and/or, Motor storage. However, few, if any, focused on motor life and reliability and many programs had cross purposes.
The objective of any true motor management program is to extend the effective useful life of the motor system combined with continuous improvement of the system. This includes:
Energy improvements
Motor system maintenance
Motor system reliability
Repair vs replace decisions
Covers the incoming power to the driven load
Definition: Motor system maintenance and management is the philosophy of continuous improvement of all aspects of the motor system from incoming power to the driven load. It involves all components of energy, maintenance and reliability from system cradle to grave.
