Permanent Magnet brushless (PMBL) machines have become more widely used for a variety of industrial application, since they inherently offers high efficiency, high power density, and maintenance free. However, as is well known, flux control capability of PMBL machines is much more difficult to achieve than that in electric machines with DC excitation… CONTINUE READING
