A motor controller is configured to control a motor including a plurality of winding groups. The motor controller includes a plurality of processors (51; 61). Each of the processors (51; 61) is configured to independently control supply of driving electric power to each of the winding groups. When an abnormality occurs in which a torque to be generated in one of the winding groups is smaller thanan individual rated torque and when a target overall torque is larger than a total of the individual rated torque for the winding group in which the abnormality does not occur, the processor (51; 61),controlling supply of driving electric power to the winding group in which the abnormality does not occur, out of the plurality of processors (51; 61) controls supply of the driving electric power such that the winding group generate a torque larger than the individual rated torque.
一种电动机控制器被配置成控制包括多个绕组群的电动机。电动机控制器包括多个处理器(51;61)。处理器(51;61)中的每一个被配置成独立地控制向每个绕组群供应驱动电力。当发生绕组群之一中要产生的扭矩小于个体额定扭矩的异常并且目标总体扭矩大于未发生异常的绕组群的个体额定扭矩的总和时,多个处理器(51;61)中的用于控制向未发生异常的绕组群供应驱动电力的处理器(51;61)控制驱动电力的供应以使得绕组群产生大于个体额定扭矩的扭矩。
