Abstract
Provided is a motor control device in which, with a position detection signal corresponding to a phase with a first reference Hall edge forming a first Hall stage, which is a minimum counter value, defined as a first reference position detection signal, and with a position detection signal corresponding to a phase with a second reference Hall edge forming a second Hall stage, which is an intermediate value, defined as a second reference position detection signal, for a first detection error with the first reference position detection signal used as a reference and a second detection error with the second reference position detection signal used as a reference, a correction coefficient calculated from one of the first and second detection errors is selected and set based on whether the first and second detection errors include a negative value.
