Abstract
A motor control device is configured to execute vector control on driving of a three-phase motor according to a d axis current command and a q axis current command. The motor control device includes: a current detection unit configured to detect a current to be input to the three-phase motor; and a control unit configured to control driving of the three-phase motor. The control unit includes: a three-phase to two-phase conversion unit configured to acquire a q axis current value by converting a three-phase current input to the three-phase motor and detected by the current detection unit into a two-phase current; and a determination unit configured to determine that the three-phase motor is idling when the q axis current value is equal to or smaller than a determination threshold set in advance.
