These two terms are often used in the motor repair industry to describe a type of insulation finishing process used on rewound electric motors. When a motor is rewound, it must be processed in some type of varnish in order to hold the windings together. This varnish, also known as resin, helps to bond the […]
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 […]

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 […]
How do you safety test lifting magnets?
When inspecting or servicing a lifting magnet, please keep in mind the following safe testing procedures: 1. Lockout/tagout all energy sources prior to testing the magnet. 2. Double-check for voltage at the lifting magnet prior to disconnecting it 3. Verify lockout/tagout. 4. Probe the cable with sharp voltmeter leads or use a tic tracer. 5. […]
