Abstract: Electromagnetic vibration is one of the vital factor causing noise and vibration of induction machine, especially in inverter supply. For inverter-fed induction machine, higher harmonic in stator current will worsen the electromagnetic noise and vibration. In this paper, a 2-D field-circuit coupling analysis by time-stepping finite element method (FEM) is conducted to get the radial electromagnetic forces in different slot combination. It focuses on the order and the frequency spectrum characteristics of radi…
