    Two aspects of shielding are of practical significance. (1) The ability of materials to provide shielding against fast electric field transients. This shielding is particularly relevant to protecting sensitive semiconductor devices and microelectronic assemblies during carriage through environments where the electrostatic conditions cannot be controlled. It is also relevant to protect the operatio... View full abstract»

    While power quality is basically voltage quality, it is not strictly a voltage issue. Since the supply system has a finite, rather than an infinite, strength, currents outside the direct control of the utility can adversely affect power quality. These are harmonic load currents, lightning currents, and fault currents. How do we quantify voltage aberrations indicative of power-quality problems? One... View full abstract»

    Designers are constantly facing the challenges of packing more and more functionality into ever-smaller spaces while improving power and performance. Mechanical overload protection for drive-train systems has long been desirable but, in the past, has required bulky and expensive slip-clutch mechanisms. Tolerance rings have traditionally been used to compensate for machining tolerances or different... View full abstract»

    The successful long-term operation of DC motors and generators, like the operation of any piece of industrial equipment, requires maintenance. Scheduled, periodic, visual inspections and the recording of this data are valuable information when reviewing that machines' performance. These written inspection reports serve much better than the memory of the maintenance technician or supervisor when qu... View full abstract»

    Numerous bearing systems are used in the electric motor industry. These systems even vary for a given manufacturer based on the motor size, type, enclosure, speed, and application. This article focuses on anti-friction rolling-element, grease- or oil-lubricated bearings used in vertical and horizontal motors. Although common in large motors, the hydrodynamic sleeve and plate-type bearings are beyo... View full abstract»

    Transient-voltage surge suppression (TVSS) is necessary for most electronic and computer devices exposed to telecommunications or power lines. The design of effective TVSS devices is discussed in the paper. A complete TVSS system consists of shunt protectors on the input and output. Other components may include the input shunted with a capacitor and an inductor placed inline. The grounds are isola... View full abstract»

    When unexpected bearing losses were questioned at a paper mill, work began at the mill that led to a long-term investigation to determine the causes and incidence of a type of bearing damage called "bearing fluting." It was discovered that many paper machines have bearing fluting that has caused significant down time and increased maintenance costs. Additionally, bearing fluting was found to be as...

    Sulfur-rich environments, such as those found in the paper and pulp industry, create a special problem with the silver plating in switchgear and motor control centers (MCCs). Silver plating is used throughout switchgear because of its superior conductivity and longevity. Silver is very sensitive to the presence of hydrogen sulfide (H2S), which forms silver sulfide (Ag2S), eve... View full abstract»
