How Hall-Effect Sensors Impact Motor Energy UseAutomation World, January 22, 2014
It’s been widely reported for years now that industry is the biggest global user of energy and that the motors used in industry are responsible for much of that energy use. According to a report from ABB, industry accounts for 42 percent of the global energy use, with electric motors using 2/3 of that energy.
To help address this issue, a great deal of attention has been focused on one of the more common motors used in industry—the brushless DC (BLDC) motor. A well-recognized method of improving the efficiency of BLDC motors is the incorporation of Hall-effect sensors.
