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 ...

Carrier Injection Sensorless (CIS) rotor position estimation for electric machines depends on the rotor saliency "seen" from the stator terminals. Compared to permanent magnet and induction machines, ...

Renault has been granted a patent for a wound rotor design for electric machines. The rotor includes a shaft with a slipring, winding wire, and n wound poles wound in ascending order around the main ...

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 ...

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 ...
