Magnetic Decoupling: Basis to Form New Electrical Machines

Power Electronics and Drives
Magnetic decoupling principle when applied to electrical machines states that if two windings are configured for different number of pole pairs, they would not interact with each other magnetically even though they share a common magnetic core.
