Title:
MOTOR AND MANUFACTURING METHOD OF MOTOR
Document Type and Number:
Japanese Patent JP2019058015
Kind Code:
A
Abstract:
To suppress a reduction of rotation detection accuracy of a rotor by a detection portion and a detected portion, and to suppress interference between the detected portion and a magnetic shield member at the time of assembling.SOLUTION: A motor 10 has a rotor 14 having a rotation axis 12, and a stator 18. Further, the motor 10 has a resolver rotor 16 which rotates integrally with the rotor 14, a resolver stator 20 detecting a rotation of the rotation axis 12 by detecting the rotation of the resolver rotor 16, and a holder 22 formed by using magnetic material and arranged between the stator 18 and the resolver stator 20. In the holder 22, an insertion hole 22E to which the resolver stator 20 is fixed and into which the rotation axis 12 is inserted is formed. A part positioned most radial inside on an inner surface of the insertion hole 22E is positioned radial outside compared with the position most radial inside on the resolver stator 20.SELECTED DRAWING: Figure 1
