Industrial electric motors are used in a wide variety of applications. If industry needs to move something, there is often an electric motor as the driving force. Electric motors come in all shapes and sizes. Many are designed to be rewound in order to extend the life of the equipment and also the process for […]
Potato. Potatoe. Centrifugal castings. Babbitt Bearings.
Babbitt bearings are integral to all heavy industrial machinery. Babbitt bearings are sleeve bearings made of certain types of alloys, which are melted down and cast to produce the bearing surface. Babbitt bearings are used for high speed, rotating equipment, such as compressors, turbines, electric motors and large power generators (like those in power plants). The […]
Purchase a new lifting scrap magnet
Industry is seeing a trend in the number of new lifting scrap magnets being manufactured. There has been a reduction in the amount of weld and steel in many scrap handling lifting magnets. The case walls and outer poles have been thinned and accept less punishment than in the past. Some of this is due to […]
Specialty equipment repaired for power generation plants
Motors are often designed for specialty work and many are found in public utility power generation plants. This example may resemble a flying saucer at first look, but in fact is a purpose-built 2500 HP motor designed to drive a low-speed circulating water pump. These motors are part of a permanent installation and can be […]
Specialty motors: Used to help produce high-grade American steel for manufactured goods
Some electric motors are designed for a very specific purpose. These types of motors are used in a steel annealing furnace application where temperatures can reach up to 1400 degrees F. The motors have special alloy shafts and drive large fans. The fans circulate hot gasses within the furnace in order to anneal steel […]
What is VPI? What is dip and bake?
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 […]
