Document Type and Number:
Japanese Patent JP2008249136
Kind Code:
A
Abstract:
To provide a rolling bearing device suitable for preventing wrong detection by a rotary sensor when a moment load is applied.
A thin motor 100 consists of a cross roller bearing 14 having an inner ring 14a and outer ring 14b, a stator 22 supported on the inner ring 14a, a rotor 12 supported on the outer ring 14b, a motor part 16 for imparting rotation torque to the rotor 12 and a resolver 30 for detecting a rotation angle position of the rotor 12. The motor part 16, the resolver 30 and the cross roller bearing 14 are arranged on the same plane in a radial direction in this order from a radial inside.
