A motor controller includes control systems that control actuation of a motor. Each control system includes a drive circuit and a calculation unit. The calculation unit of each control system is connected to an independent rotation angle sensor. The calculation units include master and slave calculation units. The master and slave calculation units control actuation of the corresponding drive circuit based on a current instruction value calculated by the master calculation unit and a detection result of the rotation angle sensor connected to the master calculation unit. When the detection result of the rotation angle sensor connected to the master calculation unit is abnormal, the master and slave calculation units each use a detection result of the rotation angle sensor connected to the slave calculation unit to control the actuation of the corresponding drive circuit.
