Summary:PURPOSE: An electrical apparatus with a stator core is provided to offer high performance and high rigidity with a structure which can be easily assembled by increasing an area in which the stator core and a rotor face each other and having a large contact area between the end portion of the stator core and an end brackets. CONSTITUTION: Annular positioning stepped portions(35, 36) are respectively formed at outer peripheral corner portions(33, 34) of a stator core(3) to extend over the entire outer circumference of the stator core. An annular positioning projection portion(54) is formed at a first end bracket(5). The annular positioning stepped portion of the stator core and the annular positioning projecting portion of the first end bracket are completely fitted with each other and a first end bracket. An annular positioning projection(74) is formed at a second end bracket(7). The annular positioning stepped portion of the stator core and the annular positioning projecting portion of the second end bracket are entirely fitted with each other with the second end bracket.
