Title:

回転検知装置及び回転検知方法

Document Type and Number:

Japanese Patent JP6417699

Kind Code:

B2

Abstract:

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.
