The first stator cores of the first and second stator assemblies are welded together at outer peripheries of the first stator cores of the first and second stator assemblies. The welded portion may be covered by the terminal block of one of the first stator assembly or the second stator assembly on an outer side in the radial direction with a predetermined space between the welded portion and the terminal block. | 2020-04-16 |
