Abstract
To provide rotors and rotating electric machines with high efficiency characteristics over a wide range. [Solution] According to the embodiment, the rotor 20 comprises a first rotor 100 and a second rotor 200. The first rotor 100 includes a first rotor shaft 110, a first rotor core 120 including a flux barrier band which is a region in which non-magnetic regions and bridges are continuously arranged, and two first rotor magnets arranged within the flux barrier band so as to sandwich the d-axis. The second rotor 200 is provided within the flux barrier band so as to be able to rotate relative to the first rotor 100 around a second rotation axis CX. As the rotational position of the second rotor 200 changes, the magnetic path within the first rotor 100 changes.
