Radial Force Analysis of a Single-Phase Permanent Split Condenser Induction Motor with skewed slots

사구 슬롯이 있는 콘덴서 구동형 단상 유도 전동기의 Radial force 해석

This papar presents an analysing method of radial force densities acting on each stator tooth of an induction motor with skewed slots. Two-dimensional finite element method is used for electromagnetic Held analysis of an induction motor, and skew effects are considered by coupling several disks cut by planes perpendicular to the shaft. Radial force densities as a source of vibration are calculated along the surface elements of each stator tooth and its time harmonics are examined by discrete Fourier decomposition.
