Field Harmonics in Induction Motors

ABOUT 40 papers have been written on the asynchronous torques, synchronous cusps at running, synchronous cusps at standstill (dead points), and noise of the induction motor. The subject has been also treated in some textbooks.∗ My aim is to give a coherent representation of the harmonic problem in induction motors. It is based on the work of my predecessors, on my own work, and on my experience.
