Abstract :
The anisotropy of the lamination material, which is usually negligible in the fundamental wave behavior of inverter fed machines, influences the transient control signals and may act as a disturbance during operation. The anisotropy is determined by torque measurements of lamination sheets as well as by the evaluation of the transient electrical behavior of inverter fed induction machines and can produce errors up to 40%.
