Publication number: 20210285797Abstract: A rotation detection device includes: a detector arranged with a gap to a rotating body in which rotation position information is periodically provided at regular intervals, and detecting a magnetic change as a rotation position of the rotating body; and a signal processor acquiring the rotation position information. The detector has first and second magnetic elements arranged with an interval of a/2 in a rotation direction. Each regular interval is defined as a. The first magnetic element outputs a first signal having a period corresponding to the regular intervals. The second magnetic element outputs a second signal having an opposite phase to the first signal and the period. The signal processor acquires a differential signal between the first and second signals as the rotation position information.Type: ApplicationFiled: May 27, 2021Publication date: September 16, 2021Inventors: ATSUSHI KOBAYASHI, MICHIHIRO MAKITA, YUSUKE KARIYA
