Joint IEEE and ISA meeting

Intelligent Motor Control Centers
Speaker: Dave Sterlace, ABB Inc
Location: Del Tech, Stanton Campus

Dave Sterlace talked to a packed house; about 50 engineers attended.

The "intelligent" motor control center is a description of the compact and organized physical and functional layout of the elements of the center. The ABB company's latest offering for this kind of product has a general layout as shown below:

Back Side; could be against the wall

User access for maintenance and control

Objectives for a layout that: 
1. Integrates like elements and
2. Segregates by function; e.g. controls from power, high and low voltage, controller and starter
are:

  • Design flexibility
  • Reduce wiring complexity
  • Segregating, for example, high voltage from low voltage promotes a safer installation
  • Increase process uptime
  • Save energy through better control of function
  • User friendly control interface
  • Smaller physical size
