Abstract
A motor control device is configured to control a motor as a dynamic force source depending on a position of a rotation detection object that rotates while interlocking with the motor, the motor and the rotation detection object being included in a mechanical apparatus including a plurality of constituent elements that interlock with each other. The motor control device includes a computation circuit configured to compute an absolute rotation angle of the rotation detection object, using a relative rotation angle of a first constituent element of the mechanical apparatus that is detected through a relative angle sensor provided in the mechanical apparatus, and a rotation number conversion value resulting from converting an absolute rotation angle of a second constituent element of the mechanical apparatus that is detected through an absolute angle sensor provided in the mechanical apparatus, into a rotation number of the first constituent element.
