摘要：
This paper presents development of an experimental induction motor core model for measuring rotational magnetostriction under practical PWM magnetisation. It was found that the magnetostrictive strain (measured with strain gauges) at stator teeth is much greater than that in other regions due to the influence of Maxwell force in the air gap. The magnetostriction on the motor core was also compared with that measured from a rotational single sheet tester.
