摘要：
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 radial electromagnetic force through the fft result in time and space domain. After the comprehensive analysis, it provides a proper kind of slot combination of inverter-fed motor to guide the industrial design
