Description: |
| "My invention relates more particularly to polyphase asynchronous induction motors having a shunt characteristic and capable of being operated at a plurality of speeds, the several speeds being obtained either by providing the stator with a plurality of polyphase windings each producing a different number of poles or by so arranging one polyphase winding on the stator that its connections can be reorganized to produce different numbers of stator poles." |
