ABSTRACT:
The rolling bearing with a built-in motor includes a bearing part including an inner ring, an outer ring and a plurality of rolling elements, and a motor part including a stator and a rotor for driving and rotating the inner and outer rings of the bearing part with respect to each other. In the rolling bearing, the bearing part includes a first bearing ring having a cylindrical-shaped inner fixing portion formed in one end face of the inner ring so as to be coaxial therewith, and a second bearing ring having a cylindrical-shaped outer fixing portion formed in one end face of the outer ring so as to be coaxial therewith. When viewed in the radial direction of the rolling bearing, the stator and rotor are interposed between the inner fixing portion of the first bearing ring and the outer fixing portion of the second bearing ring.
