Abstract
Official abstract text for this publication.
A rotation detector detecting rotation of a rotor, based on a signal produced according to rotation of the rotor, having a waveform according to a rotational cycle thereof, includes a signal obtaining unit to obtain two signals having phases different from each other; a vector operating unit to determine a vector according to a rotational angle of the rotor, based on the two signals; and a rotation detecting unit to detect rotation of the rotor, based on the vector. The two signals are produced from two elements located at positions farthest in a rotational angle of the rotor among plural rotation detecting elements located at positions different from each other.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotation detector for detecting rotation of a rotor, based on a signal produced according to rotation of the rotor, having a waveform according to a rotational cycle thereof, comprising: a signal obtaining unit configured to select from signals produced from plural rotation detecting elements including plural sets of rotation detecting elements and individual rotation detecting elements in each set of the plural sets of the rotation detecting elements bein…
