Patent number: 9341189Abstract: A fan includes a motor and an impeller. The motor includes a stationary portion and a rotating portion rotatably supported by the stationary portion. The stationary portion includes a stator and a bearing portion arranged inside of the stator. The rotating portion includes a rotor magnet arranged radially outside the stator; a shaft inserted in the bearing portion, and having an upper portion fixed to the impeller directly or through one or more members; and a thrust portion arranged axially opposite the bearing portion, and including an annular surface arranged around the shaft.Type: GrantFiled: June 14, 2012Date of Patent: May 17, 2016Assignee: NIDEC CORPORATIONInventors: Teiichi Hirono, Shinichiro Noda, Yoshiharu Ikegami, Tomohiro Hasegawa, Tomohiro Yoneda, Shunji Matsumoto, Seungsin Yoo, Kouta Kabune

Patent number: 9316229Abstract: A base plate of a motor includes an inner bottom plate portion and an elevated portion. A land portion is arranged on an upper surface of a portion of a circuit board which overlaps with the inner bottom plate portion in a plan view, or on a portion of the circuit board which overlaps with the elevated portion in the plan view. A conducting wire extending from a coil is electrically connected to the land portion. This structure enables the conducting wire to be connected to the land portion on the circuit board without the conducting wire being drawn outward beyond an outer circumferential end portion of the base plate. The axial position of the conducting wire connected to the land portion and the axial position of the base plate at least partially overlap with each other.Type: GrantFiled: March 5, 2013Date of Patent: April 19, 2016Assignee: NIDEC CORPORATIONInventors: Takehito Tamaoka, Kazuhiko Fukushima, Hiroaki Hirano, Kouta Kabune
