Detent force is the main component of thrust ripple which is one of the unique characteristics of permanent magnetic linear synchronous motor (PMLSM). This paper briefly analyzes the causes and features of the detent force, and presents an improved structure of PMLSM on the basis of position shift and phase shift superposition method of multiple motors. The finite element method is used to simulate...
Kinetic energy of a vibrating object in vehicles is normally absorbed in a form of thermal energy by mechanical dampers and other facilities. So the energy of the vibration is consumed wastefully. Using electrical shock absorber, energy of the vibration is converted into electrical energy. The electrical shock absorber consists of a permanent magnet tubular linear synchronous motor (PMTLSM), a spring...
