Provided is an electric motor in which an imbalance in electromagnetic force is inhibited even when an abnormality has occurred in an electric power system. The motor (1) is connectable to a plurality of electric power systems (D1, D2) and includes: a stator (8) including a plurality of excitation magnetic poles (12) disposed in a circumferential direction and coils (U1, V1, W1 (U2, V2, W2)) provided on the respective poles (12), the coils including, for each of the systems (D1, D2), a set of three or more phase coils, the coils carrying respective currents of three or more phases of the corresponding system (D1, D2); and a rotor (9) rotatable relative to the stator (8). The coils (U1, V1, W1, U2, V2, W2) of the stator (8) are arranged such that coils adjacent to each other in the circumferential direction are different in phase and associated with different systems.
