Beschreibung
Zusammenfassung:	A rotor apparatus includes: a rotor configured to rotate around a rotational axis; an angular position identification layer disposed to surround the rotational axis and configured to rotate according to rotation of the rotor, and having a width varying with angular positions of the rotor; and an angular range identification layer disposed to surround the rotational axis and configured to rotate according to the rotation of the rotor, and configured such that a plurality of portions of the angular range identification layer respectively corresponding to a plurality of different angular position ranges of the rotor have different overall widths.
