Electric motors are available for a wide range of applications and in a variety of power outputs. They are the ideal drivers for a huge number of operations. Electric motors are the primary mover for a vast majority of industrial and tertiary sector activities. Some motors are visible as a separate entity; others are built into boxed applications such as air compressors, heat pumps, water pumps, and fans. Electric motors account for approximately 65% of the electricity consumed by EU industry.
Despite their importance, they are rarely viewed as a production asset in their own right. However, they should be since the manner in which they are purchased, maintained, and replaced can make a major difference in profitability. When motors are not managed optimally, the result is higher energy losses and—even more significantly—a reduced reliability and availability at the production site.
Early replacement of electric motors is a rare practice. In most companies, motors run to failure. Once failure occurs, they are repaired or replaced as quickly as possible. Replacement typically takes place without considering more than the basic technical requirements.
A more detailed look at all cost factors reveals however, that an early replacement of an electric motor is often paid back in a very short time. This payback is fed by improved energy efficiency, by reduced maintenance costs, and by avoiding unplanned outages and their associated losses.
Electric motors are a forgotten asset. By making them subject of a full asset management programme, companies can improve their performance and gain a competitive advantage.Log in to post comments
