A plurality of motors (71, 72, 73, 74) and a plurality of batteries (21, 22), which drive the output shafts (31, 32), are connected so as to supply power from the batteries to motor groups comprising the motors that drive the respective output shafts. When an abnormal motor determined to be abnormal is in a driving state, the electric moving body (10) switches the abnormal motor to a stopped state, and switches one of the motors in the stopped state among the motors for driving an output shaft driven by the abnormal motor to the driving state. A motor of a motor group including an abnormal motor and a motor of a motor group including a switching motor are assigned to a driving state and a stopped state so that at least one motor drives each output shaft, and each battery supplies power to the at least one motor.
驱动各输出轴(31、32)的多个电动机(71、72、73、74)和多个电池(21、22)以从各电池向由分别驱动不同输出轴的电动机构成的各电动机组供电的方式连接。电动移动体(10)在判定为异常的异常电动机处于驱动状态的情况下,将异常电动机切换为停止状态,并且将对异常电动机所驱动的输出轴进行驱动的电动机中的停止状态的电动机之一切换为驱动状态,将包含异常电动机的电动机组的电动机和包含切换电动机的电动机组的电动机分配为驱动状态和停止状态,以使至少一个电动机驱动各输出轴,并且各电池向至少一个电动机供电。
