Examination of the effect of manufacturing error of small magnetic levitation motor using flexible PCB winding on characteristics

Abstract

　In recent years, a wide variety of motors have been used, but when manufacturing motors with different structures, it is necessary to make major changes to the winding manufacturing equipment, which causes an increase in cost. Therefore, the authors propose to manufacture the motor winding using a flexible PCB. In the proposed method, if there is no big difference in the structure and dimensions of the substrate, a winding with a high winding density can be easily manufactured at a relatively low cost. In this paper, we have manufactured a small magnetic levitation motor using windings manufactured using flexible PCB technology and investigated the effect of manufacturing error.
