Zusammenfassung:	A motor controller for controlling a brushless DC motor is provided. The motor controller includes a vector control unit configured to perform a sensorless vector control on the brushless DC motor in accordance with an input command value; a storage portion configured to store time-series control target values so that an amount of rotation angle of the brushless DC motor transitions in a same manner as an expected pattern; and a command portion configured to input, to the vector control unit, the control target values serially as the command value.
