Electric motor winding failures can develop from several reasons, such as over greasing, a voltage surge, poor power, contamination or insulation problems. A voltage surge caused so much force that it ripped the winding apart creating shorts and grounds in a 2500 horsepower motor. CMT can determine if it’s a mechanical or electrical failure in […]

Railroad motors operate in harsh conditions – wind, snow, heat and rain – in order to get shipments all across the country. Railroad traction motors drive axles and are designed in many sizes. Diesel-driven generators are also found in the railroad industry. At railroad yards, there are 360-degree rotation motors or winch drives for lifting […]
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.
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 […]
Journal bearings are a housing shell or metal sleeve that allows a shaft to rotate freely inside while the assembly is structurally supported. Numerous journal bearing applications exist: Journal bearings can be used in low-speed operations (5 rpm or less) in a grease lubricated brass sleeve. Pictured is an oil ring lubricated Babbitt bearing in […]
April is Earth Month, and we can think of nothing more greener than an electric motor rewind. An electric motor rewind can be done to make a motor workable again without the high cost of a new motor. At CMT, we can rewind a motor in an emergency, which means your downtime is minimal. Usually, […]
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 […]
