Energy-Efficient Motors Deliver Savings
In simplest terms, energy-efficient electric motors are high-quality versions of standard motor products. They pack more of "active" electric materials (steel laminations and copper) into essentially the same physical package—hence carry a price tag 15-30% higher than their less-efficient cousins.

Honeywell hosts hot user symposium
Phoenix, AZ—It was hard to tell which was hotter, an outdoor temperature of 107 ºF or the networking at Honeywell Users Group (HUG) Americas Symposium held here, June 9-13, 2003.
`Division’ or `zone’ by any other name is still hazardous
Expanded online version of May 2003 Control Engineering‘Back to Basics.’ Click here to read the main article Not all parts of processing plants or manufacturing facilities are created equal. In fact, some production areas can be downright hazardous. Petrochem plants, underground mines, even grain silos pose the potential of accidental explosion, due to ignitable gases, vapors, or dust that may be present. Various classification systems have been set up to identify these potentially dangerous industrial environments so that electrical equipment operating in those areas can be regulated to prevent ignition and explosion, thereby ensuring the safety of workers and facilities. Two main classification systems have emerged, differing in details that reflect their regional origins: A North American system based on the U.S.
Switched-Reluctance Motors and Controls Offer an Alternative Solution
Online Extra to Feb. 2003 Control Engineering article,‘Springtime for Switched-Reluctance Motors?’ Click here to return to main article Switched-reluctance (SR) technology offers users a simple, rugged type of electric motor, able to deliver high torque and speed. However, control electronics and a sophisticated drive are required to obtain such high-performance from these machines.

In this issue: MV drives, ashore and under water Open-loop steppers dominate DSP potpourri New digital dc winder drive Unidrive now available in 230 V Control Engineering in June User aids Major Motion Control Symposium Worth reading Medium-voltage ac drives on the move - ashore and under water Rejuvenated medium-voltage (MV) ac drives are making some agile moves for such large sized equipment. On May 26, ABB (Turgi, Switzerland) launched its ACS 6000 MV ac drive family, rated from 6 to 27 MW at supply voltages up to 3.3 kV. This extends the range of ABB's MV drives substantially above 5 MW provided by ACS 1000-launched in late 1997.
