回転電機
Document Type and Number:
Japanese Patent JP5850259
Kind Code:
B2
Abstract:
A housing and a rotary shaft of a motor are formed of non-magnetic material. A soft magnetic member is provided between a first axial end surface of a fixed core and a bearing. The soft magnetic member is provided on the fixed core side relative to the first bearing thereby to suppress magnetic flux leaking to a vicinity of one end part of the rotary shaft by leading the magnetic flux, which is generated from a rotor, to the rotor core through the fixed core and a casing. A magnetic angular position sensor fixed to one end part of the rotary shaft can detect a magnetic angular position of the rotor accurately without being affected by external magnetic field. As a result, noise generated by vibration of the motor can be suppressed.
