摘要： In the present spinning method using elements including: a tube material (102); a pair of chucks (101a, 101b) which hold both ends of the tube material (102); and a roller (103) having a predetermined curved shape in order to shape the tube material (102), in a state that circumferential portions at the both ends of the tube material (102) are fitted in and held by circumferential grooves (104) provided on side surfaces of the chucks (101a, 101b), the method includes a step of transferring a curved shape on a side surface of the roller (103) to a side surface of the tube material (102) by rotating the chucks (101a, 101b) which hold the tube material (102) around a first axis (J1), rotating the roller (103) around a second axis (J2), moving the rotating roller (103) in an X direction, and pressing the side surface of the roller (103) against the side surface of the tube material (102) between the rotating chucks (101a, 101b).

摘要： A rotating electrical machine includes: a claw pole stator constituted with a stator core that includes a plurality of claw poles and a stator coil wound inside the stator core; and a rotor rotatably disposed at a position facing opposite the claw poles. The stator core is constituted of split blocks each corresponding to at least one of magnetic pole pairs each made up with two claw poles assuming different magnetic polarities when an electric current is supplied to the stator coil.
