Patent number: 9071118Abstract: An axial motor includes a rotor arranged between a pair of stators with coils. In the rotor, a plurality of permanent magnets sandwiched between pairs of first magnetic materials and a plurality of second magnetic materials are alternately arranged in a rotation direction while gaps are provided therebetween. Since the permanent magnets are sandwiched by the first magnetic materials in the thus constructed axial motor, a field-weakening control can be performed. Since the second magnetic materials are provided, a reluctance torque can be generated. Further, since the gaps are provided, more magnetic fluxes generated from the permanent magnets can be caused to flow toward the coils. Therefore, the thus constructed axial motor can achieve a higher output, higher torque, higher efficiency, and miniaturization.Type: GrantFiled: June 17, 2010Date of Patent: June 30, 2015Assignees: NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY, KABUSHIKI KAISHA KOBE SEIKO SHOInventors: Masatsugu Takemoto, Hiroyuki Mitani, Hirofumi Hojo, Koji Inoue, Osamu Ozaki
