ROLLING BEARING DEVICE WITH UNIT ATTACHMENT STRUCTURE OF ROTATION SENSOR AND ROLLING BEARING DEVICE WITH UNIT ATTACHMENT STRUCTURE OF DRIVING BODY

摘要

PROBLEM TO BE SOLVED: To provide a rolling bearing device suitable for preventing erroneous detection of a rotation sensor when a moment load is applied.

SOLUTION: A thin motor 100 is provided with a cross roller bearing 14 having an inner ring 14a and an outer ring 14b, a stator 22 supported by the inner ring 14a, a rotor 12 supported by the outer ring 14b, a motor part 16 imparting rotation torque to the rotor 12, and a resolver 30 for detecting a rotation angle position of the rotor 12. The resolver 30, the cross roller bearing 14 and the motor part 16 are arranged on a radial same plane from a radial inner side in this order, and a coil 16b and a resolver stator 20 are constituted as an attachable and detachable unit.
