The invention describes an electrical machine comprising an armature (20) with armature slots (24) for accommodating armature coils and a commutator (10) with commutator laminates (11), wherein at least one armature coil is formed from two coil elements (25, 26), which are arranged symmetrically with respect to one another in relation to the axis of rotation (21) of the armature (20). The electrical machine is characterized in that the number of commutator laminates (11) is an integral multiple of the number of armature slots (24).
