Patent number: 11201521Abstract: A hybrid stepping motor has a connector housing formed integrally with an insulator having an upper insulator and a lower insulator. The hybrid stepping motor includes a stator core and output terminals concentrically disposed outside the stator core. A wiring pattern serving as the output terminals has connector pins and land portions disposed eccentrically with respect to one another. The land portions are formed on an outer edge side of the wiring pattern. A surface, which is an uppermost surface of the wiring pattern, is located below a lowermost surface, in which jumper wires and lead wires pass, of the lower insulator. The lead wires are pulled out from a lower side, and are pulled out to guiding grooves.Type: GrantFiled: March 3, 2016Date of Patent: December 14, 2021Assignee: MINEBEA MITSUMI INC.Inventors: Takamasa Inuzuka, Mitsushi Goto, Masaaki Matsubara, Tomohisa Suzuki, Atsushi Taroda

Patent number: 10113551Abstract: A axial flow fan includes an impeller having a plurality of blades, a motor arranged to rotate the impeller, and a casing accommodating the impeller and the motor. The casing includes a cylindrical housing, a motor base configured to hold the motor, and a plurality of spokes connecting the housing with the motor base. The plurality of spokes include a spoke having a straight shape and a spoke having a curved shape that is convex toward a rotational direction of the impeller. The axial flow fan further includes a lead wire for supplying electric power to the motor. When a radial length of the spoke having the straight shape is defined as L and an amount of the curvature of the spoke having the curved shape is defined as X, a displacement of the curved shape (X/L) is less than 0.2.Type: GrantFiled: March 18, 2013Date of Patent: October 30, 2018Assignee: MINEBEA CO., LTD.Inventors: Atsushi Taroda, Takako Otsuka, Masaki Ogushi, Yoichi Kawai
