Abstract

An electric rotating machine (M) comprises: a stator (100) having drive stator windings (101) which generate a stator-side magnetic flux upon supply of alternating current; and an outer rotor (200) having drive rotor windings (201) with which the stator-side magnetic flux generated by the drive stator windings (101) is coupled and which is generated by generating a torque between the rotor-side magnetic flux generated by the drive rotor windings (201) and the stator-side magnetic flux. The electric rotating machine has an inner rotor (300) having a DC-excited stator winding (102) which generates a magnetic flux when supplied with a direct current by converting the alternating current supplied to the drive stator windings; and an inner rotor (300) having alternating current induction rotor windings (301) which induce an alternating current from the magnetic field generated by the DC excited stator winding of the second stator. The current flowing through the AC induction rotor windings is provided to the drive rotor windings of the outer rotor.

Description

technical field [0001] This invention relates to rotating electric machines of the secondary excitation induction machine type. Background technique [0002] A rotating electrical machine is mounted in various devices as a power source, and for example, it is mounted alone in a vehicle to function as a power source for an electric vehicle, or mounted together with an internal combustion engine to function as a power source for a hybrid vehicle. [0003] As a rotating electrical machine, an induction machine is known that supplies an alternating current to a winding coil on the stator side to generate a rotating magnetic field, and causes the winding coil on the rotor side to generate an induced current by electromagnetic induction, whereby the rotating magnetic field on the stator side and the rotor side Torque is generated between the winding coils. [0004] Among such induction machines, various studies have been conducted on a secondary excitation induction machine in wh...
