摘要： A switched reluctance motor has a rotor and a stator. The stator has first and second stator magnetic pole groups sequentially placed in an axial direction of the rotor. First and second stator magnetic poles in each group are alternately arranged on a same circumference. The first stator magnetic poles are placed every electrical angle 2π and reversely magnetized to each other. The second stator magnetic poles are placed every electrical angle 2π and reversely magnetized to each other. The first magnetic pole is apart from the second magnetic pole by electrical angle π. Each stator magnetic pole in the first stator magnetic pole group is apart from that in the second magnetic pole group by electrical angle π/2 in the circumferential direction.

摘要： A rotor includes a rotor core comprised of magnetic steel sheets laminated in the axial direction and a pair of end plates that are respectively provided on the axial end faces of the rotor core so as to together sandwich the rotor core in the axial direction. The rotor is rotatably disposed in an electric rotating machine with a circumferential surface of the rotor core facing a stator. At least one of the end plates is configured to have through-holes, each of which is formed so as to axially penetrate the end plate, and a pressing portion that is radially positioned on the stator side of the through-holes. The pressing portion abuts a corresponding one of the axial end faces of the rotor core and exerts an axial load on the corresponding axial end face of the rotor core by an elastic force of the end plate.

摘要： A rotor includes a rotor core comprised of steel sheets that are laminated in the axial direction of the rotor core and a rotating component configured to rotate together with the rotor core. Each of the steel sheets has a positioning portion for circumferentially positioning the steel sheet with respect to the rotating component and is formed of a rolled steel material. For each of the steel sheets, the direction of rolling of the steel sheet is circumferentially offset from both imaginary lines X and Y by predetermined angles. Each of the steel sheets is shaped so that the circumferential position of the positioning portion thereof remains unchanged when the steel sheet is front-back inverted about the imaginary line X. When viewed along the axial direction, at least one of the steel sheets is front-back inverted with respect to and thus forms a mirror image of the other steel sheets.
