Rotating electrical machines with rotors limiting magnetic flux loss, in particular electric motors

摘要

The present invention relates to a rotor shaft formed of a rotor body having a plurality of stacked plates (16) and installed on a rotor shaft (14), wherein the plurality of plates comprise an outer edge portion (36) and an inner edge portion (10) having a housing (40) for accommodating a magnetic flux generating part (20) and a magnetic pole expanding part (42) located between the stator (12) and the stator (12). According to the present invention, the magnetic pole expansion portion (42) is connected to the inner edge portion (38) of the plurality of plates by a connection bridge (48).(FIG.
