Vertical motors are used in pumps, gearboxes, grinders and mills, among other industrial equipment. Vertical motors have many design specific attributes based on down thrust requirements. Many vertical motors have multiple thrust bearing sets on either the top or bottom housing and larger designs have Babbitt tilt pad and guide bearings for heavy load conditions. […]
AC motors have laminated core irons
AC motors are manufactured with a laminated core iron. Each lamination is individually insulated to prevent circulating currents within the core iron that creates hot spots. CMT will core loss test a wound stator prior to burnouts of windings in a temperature controlled, monitored oven to remove varnish and allow for easier coil removal. A […]
AC/DC: band and motors
Yes, AC/DC is a band, but AC/DC also refers to motors. AC motors are found in power plants, chemical plants, municipalities, rubber, mining and cracker plants. DC motors are found in steel mill, rail, mining, plastic and shipboard applications. CMT can repair and refurbish AC and DC motors – anything from periodic bearing maintenance to […]
CMT can keep your motor running
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.
CMT can get your motor repaired and running
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.
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 […]
Save money and production downtime with predictive maintenance programs
Predictive maintenance programs are designed to head off problems before they start. Certified technicians can tailor a plan to suit your needs and budget, while allowing the maximum uptime of your equipment. Predictive maintenance programs have the ability to diagnose, track, monitor and trend equipment, as well as correct the anomalies that are found, all […]
