摘要： Provided is a magnetic encoder which includes plural rows of magnetic encoder tracks. One magnetic encoder track of the magnetic encoder tracks includes magnetic pattern magnetized thereto to generate signals of equal pitch for detection of rotation. The magnetized magnetic pattern includes N poles and S poles arranged in alternate fashion. The magnetic encoder is configured to be employed spaced through an air gap from sensors that read magnetic signals of the respective magnetic encoder tracks. The magnetic encoder track is configured such that the magnetic pattern thereof acting on position of the corresponding sensor is, under the interference of magnetism of the plural rows of magnetic encoder tracks, detected by the corresponding sensor as an equal pitch magnetic pattern.

摘要： A magnetic encoder magnetizing method, in which magnetization of the plural neighboring tracks of the magnetic encoder can be accurately performed, is provided. While an annular magnetic body having a plurality of annular, unmagnetized magnetic encoder tracks integral therewith and juxtaposed relative to each other is rotated, the tracks of the magnetic encoder are individually magnetized by a magnetizing head, made up of a magnetizing yoke and an exciting coil, to thereby provide the magnetic encoder. In the practice of this magnetizing method, when one of the tracks of the magnetic encoder is magnetized, the other track is covered with a magnetic shielding mask.
