This paper deals with optimum design criteria of miniature type linear servo motor of precise pick & place module for detent force reduction using response surface methodology (RSM) & finite element method (FEM). The focus of this paper is to find a design solution through the comparison of detent force according to core shape variations. And then, a central composite design(CCD) mixed resolution is introduced, and analysis of variance (ANOVA) is conducted to determine the significance of the fitted regression model. The proposed procedure allows to define the machine dimensions starting from an existing motor or a preliminary design. To prove the propriety of the proposed method, the Digital Signal Processor(DSP) installed experimental devices are equipped and the experiment is performed.

This paper deals with the dynamic characteristic analysis & the intervals selection for constant speed control of primary stacks in the moving (aluminum plate) type 3D conveyer system using Linear Induction Motor. The dynamic characteristic analysis method of the vector controlled LIM using coupled FEM and control algorithm taking into account the movement is proposed. The focus of this paper is the analysis relative to selecting primary stack intervals in order to constant speed control in horizon and vertical driving conditions of 3D conveyer system using LIM.

This paper deals with the efficiency evaluations in a synchronous reluctance motor (SynRM) versus a permanent magnet assisted SynRM (PMASynRM) using a coupled transient finite element method (FEM) and Preisach modeling, which is presented to analyze the characteristics under the effect of saturation and hysteresis loss. We are focusing on the efficiency evaluation relative to hysteresis loss, copper loss, etc. on the basis of load condition in a SynRM and PMASynRM. Computer simulation and experimental results for the efficiency using dynamometer show the propriety of the proposed method and the high performance of PMASynRM.
