A motor controller includes individual drive circuits, a plurality of energization systems, and a processing circuit that outputs a plurality of individual control signals. The processing circuit executes a first calculation process, a second calculation process, a third calculation process, and a fourth calculation process for each of the energization systems. The first calculation process is a process of calculating individual current command values. The second calculation process is a process of calculating the estimated temperatures of protection targets. The third calculation process is a process of calculating individual limit values. The fourth calculation process is a process of calculating the individual control signals based on the individual current command values that are limited by the individual limit values. The processing circuit calculates the estimated temperatures of the protection targets where current of a target system flows.
