Abstract :
Should all existing electric motors in manufacturing plants be removed and replaced with new premium efficient motors? Should all existing electric motors be replaced at time of failure? Can premium efficient motors be rebuilt and maintain their design efficiency? The answer to these questions is that electric motors must be managed with special considerations of each motor and special economic considerations. This paper reviews motor losses, a study of blind tests on rewound motor efficiency and a comment where the service center knew the motor would be retested after rewinding. A recommended corporate policy is given for owners of electric motors to use in managing motors
