Straightforward motor upgrades
Many electric motors in use are either low efficiency or not properly sized for the application. This results in motors working harder than they need to, using more energy in the process. Similarly, older motors may have been rewound a few times during maintenance, lessening their efficiency. It is estimated a motor loses one to two percent efficiency every time it is rewound.
Because energy consumption accounts for 96 percent of the total life cycle cost of a motor, paying extra for a premium efficiency motor will result in a return on investment over its lifespan.
But if the motor is working, and has been working for decades, is it worth the hassle of upgrading it?
