Claim Text:
1. A motor control device comprising: a coil temperature detection unit which detects a coil temperature of a motor; an upper limit current determination unit which determines an upper limit value of a coil current in which a coil temperature after a lapse of a first predetermined time from a present time is maintained at an upper limit temperature or lower every time a second predetermined time shorter than the first predetermined time elapses by using the coil temperature detected by the coil temperature detection unit; and a coil current control unit which controls the coil current so as to be equal to or lower than the upper limit value, wherein the upper limit current determination unit is configured to determine the upper limit value of the coil current by using a present coil temperature as the coil temperature and using the upper limit temperature and the first predetermined time.
