Abstract :
The selection of a motor having a 1.15 service factor to a 1.0-service factor motor of the next larger horsepower is compared. This comparison includes first cost, losses, temperature distribution, efficiency, torque performance, and expected life of the alternate selections. In most cases, the larger 1.0-service factor machine is shown to be the preferred selection.
