Discontinuity of magnetic circuit according to the end effect is generated in the PMLSM. Due to the unbalanced magnetic state, the unbalanced inductance and unbalanced back-EMF is produced. In this paper, the effects of circulating current due to the end effect are analyzed by FEA (Finite Element Analysis). By using FEA and DOE (Design of Experiment), an optimal design of the auxiliary-teeth model...
Summary form of only given: To reduce the detent force by end effect, the auxiliary core which has the independent magnetic circuit is proposed in this paper. The auxiliary core is designed by the DOE (Design of Experiment) and FEA. And the prototype machine of auxiliary core is made and experimented. To demonstrate reduction effect of the detent force by the auxiliary core, the experimental results...
This study presents an optimal configuration of Flux-Reversal Linear Synchronous Motor (FRLSM) with the optimal number of attachment permanent magnets (PMs). The optimal model of 2000 (N) is designed to reduce detent force by redesigning the air-gap structure and skewing.
This paper deals with optimal design considered a coil temperature to maximize a force density of double sided coreless PMLSM(Permanent Magnet Linear Synchronous Motor). Optimal current density which the coil temperature is reached an allowable temperature with heat transfer analysis was applied to optimal design of magnetic circuit for maximum force density. The heat transfer analysis results are...
