An integrated assembly of an electric winding exchanger system and a multiphase electric motor comprises a housing, the multiphase electric motor, and the electric winding exchanger system. Further, the housing comprises a first housing portion, a second housing portion, and a partition. Further, the first housing portion comprises a first interior space and the second housing portion comprises a second interior space. Further, the first housing portion houses the multiphase electric motor and the second housing portion houses the electric winding exchanger system. Further, the electric winding exchanger system comprises a back electromotive force (EMF) boosting circuit comprising switches and bus bars. Further, the partition comprises openings. Further, leads of coils of the multiphase electric motor enters the second interior space through a first opening of the openings for connecting terminals of the leads to the bus bars.
