  • PdMA Tip of the Week: DC Drives

    This week's PdMA tip: DC Drives Did you know that DC Drive reliability is a major factor in the production of your automotive tires? A DC drive is designed to supply Direct Current (DC) to a DC motor. However, with a failing front end of the DC drive, more of an AC signal can be delivered resulting in high vibration, elevated temperature, poor operation and reduced life expectancy of the drive and motor. Without performing the correct analysis, the wrong decision might be to replace the DC motor. PdMA® Corporation is an industry leader in the field of predictive maintenance (PdM

  • PdMA Tip of the Week: Smaller is Bigger

    This week's PdMA tip: Smaller is Bigger DC motors are relatively simple machines consisting of an armature winding (rotating) and shunt/series windings (stationary). Energizing these two primary components of the DC motor creates two magnetic fields that push or pull each other to make the armature rotate. Recording a winding resistance value of these components is a common practice during de-energized motor testing for trending or troubleshooting. When it comes to measuring winding resistance, remember our tip that smaller is bigger. Bear in mind that the smaller the wire size, the gr

  • What You Should Know about an Arc Flash and Arc Blast

    Arc flash incidents are among the common causes of electrical injuries in a facility. These events result from a combination of heat and light emitted during a dangerous electrical explosion. With hot gasses released into the air by an arc flash, they immediately melt metals and similar materials. Copper and other metals also tend to vaporize in an explosive manner because of the high temperature. The plasma arc becomes even more powerful as vaporized metal provides this effect. Moreover, fatalities occur from arc flash incidents. Severe injuries include eyesight damage and radiation
