Lecture 13

Time harmonics in induction machines

Before class activity;

1. Watch videos of lecture and problem 7.1 and 7.11 in scalable learning 

2- Read compendium, check chapter 3 again and then chapter 7, sections 7.1, 7.2, 7.3, 7.6 and 7.7

[SEN] chapter 5 induction machines section 5.15 (5.15.2 not in EJ2201) + appendix A pp 569-581 BEWARE! error in sentence at bottom of p575 "these harmonics flux denisties induce harmonics voltages in the windings". The stator space harmonics create  induced voltages at fundamental frequency (n tops per spatial period rotating at w1/n -> fundamental). It is the rotor space harmonics that create time harmonics in the stator windings.
