Development of a Wound Rotor Brushless Doubly Fed Machine Based on Slot MMF Harmonics [PDF]

2008 IEEE Industry Applications Society Annual Meeting, 2008
In the rotor winding magnetomotive force (MMF) of an ac machine, there exist so-called slot harmonics which appear in pairs and the lower order harmonic of each pair rotates in the opposite direction against the fundamental component. In addition, the slot harmonics have the same winding factor as the fundamental component.
