Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A magnetic encoder including plural rows of annular magnetic encoder tracks arranged adjacent to each other, each of the plural rows of magnetic encoder tracks being configured to be read by a corresponding sensor, comprising: an AB magnetic encoder track including a magnetic pattern having N poles and S poles arranged in alternate fashion magnetized thereto to generate magnetic signals for detection of rotation; and a Z magnetic encoder track that is diff…
