A review on recent applications of brushless DC electric machines and their potential in energy saving
Electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. Electric motors account for between 43 and 46% of all global electricity consumption approximately. They give rise to about 6 040 Mt of CO2 emissions. End‐users approximately spend USD 565 billion per year on electricity [1]. In recent years...
