| Abstract |
As interest in factory automation and smart factories expands worldwide, the demand for process equipment used in them is also increasing. in line with this trend, the development of permanent magnet linear synchronous motors (PMLSM) that can be easily combined with multiple is also actively progressing. PMLSM is possible to connect various production facilities and inspection equipment with a single line with minimal space use, and it is easy to respond to changes in related facilities. In addition it is not only enables linear motion without other mechanical parts, but also does not cause any problems caused by abraison because it does not generate mechanical contact. However, since mechanical interference between the mover and the stator may occur in PMLSM depending on the applied load, it is necessary to design the air gap differently. Therefore, the rate of change in thrust according to the air gap length was analyzed through finite element analysis for the various models with different pole pitches. |
