Direct-Driven Interior Magnet Permanent Magnet Synchronous Motors for a Full Electric Sports Car
The design process of direct-driven permanent magnet synchronous machines (PMSMs) for a full electric 4 ´ 4 sports car is presented. The rotor structure of the machine consists of two permanent magnet layers embedded inside ...
Mitigating noncirculating bearing currents by a correct stator magnetic circuit and winding design
Different mechanisms by which bearing currents flow inside the electrical machine are well studied. In contrast, investigation and development of different techniques to mitigate these currents remain a field for improvement, ...
