Beschreibung
Zusammenfassung:	A motor control device includes: a switching control unit that acquires a next Hall pattern from a predetermined Hall pattern among six Hall patterns being combinations of potentials of position detection signals that are outputs of a plurality of sensors, determines whether the next Hall pattern is different from a first Hall pattern scheduled next to the predetermined Hall pattern, and counts a number of times the next Hall pattern is different from the first Hall pattern, in which correction is suspended when the number of times the next Hall pattern is different from the first Hall pattern is greater than a predetermined number of times of abnormality, or when a rotation speed of a rotor is not being accelerated even if the number of times the next Hall pattern is different from the first Hall pattern is less than or equal to the predetermined number of times of abnormality.
