ROLLER BEARING DEVICE HAVING RADIAL-PLANE ARRANGEMENT STRUCTURE OF ROTATION SENSOR
Document Type and Number:
WIPO Patent Application WO/2009/060658
Kind Code:
A1
Abstract:
Provided is a roller bearing device, which is suitable for preventing an error
detection of a rotation sensor in case a moment load is applied. A thin motor (100)
includes 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 unit (16) for applying a rotation torque to the
rotor (12), and a resolver (30) for detecting the rotation angle position of the
rotor (12). The resolver (30), the cross roller bearing (14) and the motor unit
(16) are arranged in the recited order from the radially inner side on a radially
identical plane.
