Lubrication
Motors 10 HP and smaller are lubricated at the factory to operate for long periods under normal service conditions without re-lubrication.  Excessive or too frequent lubrication may actually damage the motor
Typical Re-lubrication Intervals
Hours of Service Per Year Re-Lubrication Interval
5000 5 Years
Continuous Normal 2 Years

Products
Where three-phase power is unavailable or impractical, it's single-phase motors to the rescue. Though they lack the higher efficiencies of their three-phase siblings, single-phase motors -- correctly sized and rated -- can last a lifetime with little maintenance.

Key
Most failures result from inappropriate application. Pay careful attention to the application requirements before choosing a motor for replacement of a failed one or for a new design application. Not choosing the correct motor type and horsepower can cause repeated motor failure and equipment downtime. Obviously, you don't want to specify a motor too small for the application, thus resulting in electrical stresses that cause premature motor failure. But neither should you specify a motor too powerful -- either because of its power or its inherent design characteristics. It can also have serious effects. For example, a motor with high locked-rotor and breakdown torques can damage the equipment it drives. Also, running a motor at less than full rated load is inefficient, costing you money for power wasted.
