Digital Control of Permanent Magnet Synchronous Motors
... As with most motors the synchronous motor (SM) has two primary parts. The non-moving is called the stator and the moving — usually inside the stator — is called the rotor. Synchronous motors can be built in different structures. To enable a motor to rotate two fluxes are needed. One from the stator ...

Doubly-fed induction generator (DFIG) as a hybrid of asynchronous
... The recent interest of research in wound rotor induction machines comes from the fact that the aforesaid advantages make them ideally suited as variable speed wind-turbine generators. The rotor speed does not have to be constant and can vary with the wind velocity even though the stator is generatin ...
