| Abstract |
This paper shows that magnetic field signature in the vicinity of an inverter fed AC machine contains
high frequency components tied to winding resonances. For high frequencies, shielding effect of
magnetic stator becomes lower. External radial magnetic field exists and is directly tied to HF current
components in slots. End winding connections are not the unique radiation source. This paper
proposes an experimental approach by creating a controlled local resonance in order to get correlation
between this phenomena and external magnetic field. An analytical model of the magnetic stator HF
behaviour is also presented. |
