Did you know that industrial electric motors are a renewable resource? Rewinding an industrial electric motor is a cost effective way to get equipment up and running quickly. The outer part of a motor, called a stator, can be decades old, but with motor rewinding, it will be like a new motor and function the […]
Rewinds give motors new life
Many times an electric motor can be given new life by rewinding. Simply put, this is the process of removing the failed copper coils, making new and re-installing them in the motor core. Part of this renewal process involves a varnish treatment of some type, normally referred to a dip and bake. The varnish helps […]
Keeping cool in the summer heat
It’s hot out there, and CMT helps keep you cool. Electric power is transmitted to consumers and industry through sub-stations that use large transformers. These large transformers require cooling fans. Various types of motors and fan systems are used in these transformers, all of which CMT can fix. From the transformers, utility companies send power […]
Journal bearings keep industrial machines running smoothly
A journal bearing is designed to support a rotating shaft in a piece of electrical or mechanical equipment. The area of the shaft supported by this bearing is called the bearing journal. The shaft rotates in the bearing while a layer of lubricant separates the two parts to stop friction and make it run smoothly. […]
Teeing off on dry grounds
Did you know pumps can be found on golf courses? They help with golf course irrigation. It’s a much better golf game when the grounds are dry and the golf cart can go anywhere! CMT fixes country club and public golf course irrigation pumps quickly, so your customers can be out attempting hole-in-ones. Pumps can […]
Big or small. We do it all.
Electric motors come in all shapes and sizes. They have many different purposes. Some move air, some supply drinking water some and actually generate electricity. Many of them power large industrial equipment while others power the air conditioner or washing machine and dryer in your home. Simply put, there are very few places in this […]
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 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 […]
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 […]
