ANGULAR SENSOR

摘要

An angular sensor comprises permanent magnets (4, 5) opposed to each other with opposite poles, and a flux density detector (10) rotating between the permanent magnets (4, 5). The pole faces (11, 12) of the permanent magnets (4, 5) are curved to properly distribute the flux density between the permanent magnets (4, 5). The sensor improves its performance without an increase in cost.
