AC motors are manufactured with a laminated core iron that is insulated and wound with copper conductors. Over time, motor windings age and fail due to usage. CMT can remanufacture any size AC motors to original specifications. Our initial burnout process includes testing core loss before and after and charting oven temperature. The core iron […]
Did you know that all electric motors are supplied with a nameplate that provides voltage information? Motors are designed and efficiency rated at the balanced nameplate voltage. Deviating voltage up or down changes torque and temperature. All deviations impact motor life. CMT can identify and provide solutions to keep your motor running.
Did you know that electric motors consume 80 percent of energy required for oil and gas production? Motors in the oil and gas industry range from small ones to those with several thousand horsepower. Major motor applications are pumps, compressors and drill rigs. Since 1985, CMT has carried the distinction of being a DQS certified […]
Vacuum pressure impregnation, known as VPI, is a varnish process for electric motor insulation. The several-hour process begins with a prebake cycle to remove any moisture, the component is placed into the varnish chamber, a vacuum is pulled to remove air, varnish is introduced and the varnish chamber is pressurized. Computerized capacitance monitoring insures a […]
