Sometimes motors in service don’t replicate controlled lab conditions. Load types may be mismatched or there might be operating efficiencies like worm gearing, wear friction or bad power, which could lead to an outage. CMT can test your motors to make sure they are up and running and repair as needed.
CMT can get your motor up and running to your specifications
Purchased a replacement motor and determined it can’t be installed? CMT can help. CMT can modify shafts and mounting, if the motor design, performance and enclosure is determined to be acceptable for the application. CMT can add accessories, such as encoders, brakes, heaters, as needed to support the existing control system. Electric motors are the […]
CMT keeps power flowing
Electric utility companies rely on CMT to service many different types of equipment. In this case, we are refurbishing a set of fuse holders that are installed on 69,000 volt power lines. The fuses are designed for a quick release in the event of a power fault. These fuse holder assemblies are exposed to nature’s […]
Ball bearings make the world go ’round
If it’s mechanical and spins, chances are, there’s a bearing in it. Ball bearings and roller bearings are the two most common types of bearings used in industry. Bearings work by rolling between two surfaces to reduce friction. The bearings help shafts and parts rotate in motors and machinery. How to tell if a ball […]
Ramping up for the summer season
The sun is out. The mercury is rising. That only means one thing: Summer is around the corner. A local country club sent in their 10 horsepower pool pump motor to be inspected before its upcoming pool season. CMT dismantled, cleaned and inspected all parts and tested the circuits to ensure it was working properly. […]
Motors in harsh environments gain longer life by special repair practices
Electric motors are expected to perform in a wide variety of environments. Sometimes they are installed in areas that are wet and dirty. These harsh environments require special features to motors and frequent maintenance. CMT has a proven track record of adapting electric motors to meet tough use. Pictured is a DC motor designed for […]
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 […]
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 […]
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 […]
