Brushless wound rotor synchronous machines (BL-WRSMs) represent an evolution in electrical machine design, combining the merits of wound rotor constructions with brushless operation to enhance ...

From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...
