How do you know if a bearing is bad?
Anything mechanical that spins has a bearing in it. The two most common types of bearings are ball bearings and roller bearings. Bearings work by rolling between two surfaces to reduce friction. Ball and roller bearings help shafts and parts rotate in motors and machinery. Ball bearings are most commonly used in household appliances, such […]

Electric motor repair and re-engineering in the Valley
This 3,000 horsepower, 4,000 volt, 900 RPM AC induction fan motor’s fabricated frame showed signs of fatigue and stress. The small movements allowed by a worn out frame structure can often lead to early winding failure and Babbitt bearing failure. Additional structural reinforcement was needed prior to replacing the windings and/or bearings. The photos show […]
Large and in charge: electric motors
Large electric motors are used by public utility companies to do important work. The 2500 HP motor pictured is used to drive a large pump that provides cooling water to an electricity-producing turbine generator. These critical motors can be rebuilt many times over in order to insure the continued operation of power generating equipment. Some […]
Laser measurements for accuracy
A Coordinate Measuring Machine (or CMM) has many different uses within the apparatus service industry. Component parts can be measured to insure dimensional correctness. A CMM can also be used to verify the accuracy of the critical fits of a motor. Some examples of this would be the flatness of a motor mounting flange, the […]

Money Saver Tip: Rewind Electric Motors
An electric motor rewind can be done to make a motor workable again without the high cost of paying for a new motor. A motor can also be rewound in an emergency, thus minimizing a customer’s downtime. For example, if an AC motor fails, it usually means that the insulation or coils were damaged by […]
