磁性编码器装置以及旋转检测装置
摘要：
本发明的磁性编码器装置(3)具有：基座部(33)，其具有用于安装于旋转轴(2)的安装面(33b)；带芯架(35)，其嵌合固定在基座部(33)上；以及多列磁性编码器磁道(30)，其形成在带芯架(35)上。磁性编码器磁道(30)的各个磁极在与磁性传感器(4)面对的面对区域移动，从而检测旋转的旋转轴的角度。利用烧结金属形成基座部(33)，对其安装面(33b)实施精压。
摘要（英）：

A magnetic encoder device (3) of the present invention includes a base portion (33) having a mounting surface (33b) for mounting to a rotary shaft (2), a cored bar (35) fitted and fixed over the base portion (33), and a double-row magnetic encoder track (30) formed on the cored bar (35). Through movement of each of magnetic poles of the magnetic encoder track (30) over a region opposed to a magnetic sensor (4), an angle of the rotating rotary shaft is detected. The base portion (33) is formed of a sintered metal, and the mounting surface (33b) is subjected to sizing.
