Abstract
According to one embodiment, an electrical machine includes a rotor and an armature. The armature includes first to third stator cores, and an armature coil. The first and second stator cores are arranged along a direction of a rotation axis of the rotor. The third stator core is arranged opposite to the first and second stator cores. The armature coil is provided between the first and second stator cores. The first and second stator cores have a same shape and each include magnetic poles and a first positioning part. The third stator core includes a second positioning part. A relative phase angle of the first stator core and a relative phase angle of the second stator core in the rotation direction are set by using the first positioning part and the second positioning part.
