Abstract:
Permanent magnet and armature coil of linear flux-switching motors are all located on its primary, while the secondary is only made of simple iron. Hence, this kind of motors has special advantage on the long distance drive system and high speed lunch system. When this motor used in long distance drive system, the short primary mover is fixed under the bogie of a railway vehicle and the secondary stator is fixed between the iron rails. Hence, this kind of motors incorporates the merits of higher efficiency, higher thrust density and low cost. When this motor used in short distance and higher speed lunch system, the short secondary mover iron is design between double sided long primary stators, which can offer some merits such as simple and high reliability mover, strong ability with load. Based on the long distance drive system and high speed lunch system, the structures, operation principle, general design principle, electromagnetic performance, and drive system of the single and double sided linear flux-switching motors are analyzed in this paper. The research results show that this kind of motors has better practical value.
