WebFeb 3, 2024 · A rotor retaining sleeve is mechanically necessary in the structure of high-speed SPM machines to prevent structural failure. However, the significant eddy current loss within metal sleeves leads to a reduction in electromagnetic efficiency and serious thermal and mechanical issues. Therefore, several techniques and methods have been proposed … WebSep 12, 2024 · An electromagnetic wave consists of an electric field, defined as usual in terms of the force per charge on a stationary charge, and a magnetic field, defined in terms of the force per charge on a moving charge. The electromagnetic field is assumed to be a function of only the x -coordinate and time.
