How does a planetary defense mission intended to push an asteroid off course manage to release a torrent of boulders with the same momentum as the spacecraft? NASA’s groundbreaking experiment, the ...

Eccentricity is a critical fault in permanent magnet synchronous machines (PMSMs), and can be generally classified into static eccentricity (SE), dynamic eccentricity (DE) and mixed eccentricity (ME).

Rotor eccentricity faults can cause uneven air gaps in the generator, reducing power quality and increasing vibration noise, eventually leading to abnormal operation. Especially in high-speed machines ...
