Abstract

This chapter deals with investigation methods of MMF harmonics of spatial orders n (\( \left| {\text{m}} \right|{ = }\left| {\text{n}} \right| \ge 1 \)) excited by the currents with frequency \( \upomega_{\text{ROT}} \) in rotor loops, included in short-circuited windings: damper winding of synchronous machines and squirrel cage of induction machines (also in asymmetrical).
