Abstract |
The average thrust of the linear synchronous motors (LSM) is computed on the basis of a two-dimensional Finite-Element Method (FEM), when considering the iron and the permanent magnet non-linearity. The LSM under consideration consists of the short-primary and the long-secondary parts in various structures. The following secondary configurations have been taken into consideration: salient poles with field winding, reluctance type secondary and the equivalent of cylindrical excited form, permanent magnet segments where one was built with of surface mounted permanent magnets and one with buried permanent magnets. We compared the thrust and the attractive force at the aforesaid four motor types. |
