ROTOR, AND MOTOR PROVIDED WITH ROTOR

The invention provides a rotor equipped with an insulating member (linking member) with which it is possible to wastelessly transmit motive power from an outer-circumferential-side iron core to an inner-circumferential-side iron core while increasing the impedance of a rotor and inhibiting electrolytic corrosion of a bearing. A rotor 3 is provided with an outer-circumferential-side iron core 32, an inner-circumferential-side iron core 34, and an insulating linking member 33 linking the outer-circumferential-side iron core and the inner-circumferential-side iron core. A plurality of grooves 331, 332 disposed in a ring shape are formed on the linking member 33. The outer circumferential-side-iron core 32 has formed thereon a plurality of inner-circumferential-side recesses 321 indenting in the outer diameter direction from the inner circumferential surface 324 thereof. The inner-circumferential-side iron core 34 has formed thereon a plurality of outer-circumferential-side recesses 341 indenting in the inner dia
