Energy costs and downtime can be greatly reduced by instituting a motor management plan. Part II of this three-part series specifically addresses the establishment of a motor failure policy and the development
of purchasing specifications. Part I addressed the general aspects
of a motor management plan, including the first steps of creating a motor inventory and guidelines for motor repair and replacement. Part III will examine motor repair specifications
as well as preventive and predictive maintenance.
According to the Department
of Energy (DOE), more than
half of all electrical energy
consumed in the U.S. is used
by electric motors. To address
this, several years ago, the DOE conducted
a technical study as to what
could be done to raise the efficiency
levels of “small” motors. After years
of study and litigation, the Small Motor Rule (SMR) was passed that covers two-digit NEMA frame single- and three-phase ¼ through 3 horsepower
motors in open enclosures.
