An insightful geometrical interpretation of spectral components of the physical quantities involved in induction machines rotor faults

This paper deeply investigates features of both current space vector components in rotating reference frame and stator current sidebands in case of induction motor rotor fault. Geometrical loci described by the representative phasors at pulsation 2sω and their dependence on inertia are evidenced. The link among torque ripple, speed ripple and flux angular ripple is considered as well, obtaining a thorough understanding and geometrical visualization of related physical phenomena.
