MOTION CONTROL: A new white paper from Rockwell Automationhighlights the inherent dangers of arc flash, discusses the standards guiding arc-flash safety, and details the role that arc-resistant motor control centers (MCCs) play in helping to contain arc energy and reduce hazards.“Advances in Low Voltage MCC Technology Help Reduce Arc-Flash Hazards and Minimize Risks” discusses how changing industry standards are putting more focus on arc-flash risks, and highlights the key features and components of an effective arc-resistant MCC design. The paper stresses the importance of understanding the performance criteria that must be met before an MCC can be classified as an arc-resistant design.
According to the paper, an arc-resistant MCC is designed and built to provide a complete structural solution in accordance with defined industry standards. Arc-resistant equipment is designed to minimize arc-flash exposure by extinguishing the arc, controlling the spread of the arc or channeling the arc pressure and energy away from personnel.
The choice between helical and spur gears in gearboxes may seem straightforward. But with planetary gearboxes, however, the choice between helical and spur gears requires some additional thought. Here’s what you need to know to make the right choice.
Cas Smith is a biological engineer at Terrapin Bright Green, a consulting firm that specializes in green and sustainable design.
