Electromagnetic induction coils are widely used in a variety of applications, many of them safety-critical. The insulation around the wire in an electromagnetic coil accounts for a significant portion of the failures in solenoid-operated valves and in electric motors. This paper presents a method of detecting the degradation of insulation used in low-voltage applications by assessing changes in impedance...
The usage of polymers in bearings has been increasing in recent years due to certain valuable tribological properties, including their ability to self-lubricate and their resistance to corrosion. These advantages encourage manufacturers to use polymer bearings in corrosive and lubricant-free work environments as well as applications in which weight reduction is desirable. The objective of this study...
