Company Profile:
The atmospheric altitude (height above sea level) at which the motor will be operating; NEMA standards call for an altitude not exceeding 3,300 ft. (1,000 meters). As the altitude increases above 3,300 ft. and the air density decreases, the air stability to cool the motor decreases - for higher altitudes higher grades of insulation or a motor derating are required. DC motors require special brushes for high altitudes.
Industry:Electrical equipment
In a 3 phase supply, where the voltages of the three different phases are not exactly the same. Measured in % of unbalance.
Industry:Electrical equipment
The temperature of the surrounding cooling medium, such as gas or liquid, which comes into contact with the heated parts of the motor. The cooling medium is usually the air surrounding the motor. The standard NEMA rating for ambient temperature is not to exceed 40fC.
Industry:Electrical equipment
A synonym for voltage, usually restricted to generated voltage.
Industry:Electrical equipment
An anti-friction bearing is a bearing utilising rolling elements between the stationary and rotating assemblies.
Industry:Electrical equipment
A motor which has its winding structure completely coated with an insulating resin (such as epoxy). This construction type is designed for exposure to more severe atmospheric conditions than the normal varnished winding.
Industry:Electrical equipment
The portion of the magnetic structure of a DC or universal motor which rotates.
Industry:Electrical equipment
The housing, frame, of the motor of which there are two broad classifications; open and totally closed. There are specific types of each:
Industry:Electrical equipment
Reliance offers the industry's widest selection of motor/generator enclosures to meet specific operating needs.
Industry:Electrical equipment
The part of the motor housing which supports the bearing and acts as a protective guard to the electrical and rotating parts inside the motor. This part is frequently called the "end bracket" or "end bell."
