Electric motors account for two-thirds of all electrical energy used by industrial applications. In a motors lifetime, their maintenance costs can total more than their original price. Failures encountered can significantly impact a company's profit short-term, and multiple or repeated failures can create long-term effects on a company's ability to compete in its market. Industrial company's must be educated on maintenance and management in order to reduce the amount of motor purchases and associated costs from motor failure. In this article, Thomas H. Bishop, P.E. for our sister publication Sustainable Plant, teaches you how to make well-informed decisions about whether to repair, rewind or replace energy-efficient motors when they fail.
