Patent number: 9407127Abstract: Provided is a brushless motor insulator capable of improving workability relating to the winding of electric wires by a simple configuration. An insulator 10 includes a main body portion 11 and a mooring portion 12. The main body portion 11 includes plural wiring portions 11b radially provided so that electric wires 30 are held while being wound on the wiring portions 11b. The mooring portion 12 is disposed in the inner periphery or the outer periphery of the main body portion 11 and moors ends of winding start portions or winding end portions of the electric wires 30 of the wiring portions 11b.Type: GrantFiled: October 14, 2013Date of Patent: August 2, 2016Assignee: SANYO DENKI CO., LTD.Inventor: Yoshinori Miyabara

Patent number: 8651807Abstract: Four tapered portions are formed on an end portion of an inner wall surface of an air channel at four locations corresponding to four corners of the profile of a surface of a housing where a suction port is formed. The four tapered portions are each inclined outwardly in a radial direction of a rotary shaft from a discharge port side toward the suction port side and extending in a rotational direction of an impeller. The tapered portions each include a main portion which is shaped such that an angle formed between the main portion and an axis of the rotary shaft gradually becomes smaller from one end of the main portion located rearward as viewed in the rotational direction of the impeller toward the other end of the main portion located forward as viewed in the rotational direction of the impeller.Type: GrantFiled: April 19, 2011Date of Patent: February 18, 2014Assignee: Sanyo Denki Co., Ltd.Inventors: Naoya Inada, Toshiyuki Nakamura, Toshiki Ogawara, Yoshinori Miyabara

Patent number: 8197198Abstract: A fan system with enhanced air flow-static pressure characteristics and reduced fan noise compared to the related art is provided. The number of duct blades of a duct is the same as the number of stationary blades of an axial flow fan located in front of the duct, and the duct blades correspond to the stationary blades respectively. An end surface of a rear end portion of each stationary blade and an end surface of a front portion of a duct blade corresponding to the stationary blade have the same shape, and they align together and contact each other to form one composite stationary blade, with a discharge port of each axial flow fan communicating with an inlet port of a duct housing located behind the axial flow fan.Type: GrantFiled: May 22, 2009Date of Patent: June 12, 2012Assignee: Sanyo Denki Co., Ltd.Inventors: Yoshinori Miyabara, Jiro Watanabe, Hiromitsu Kuribayashi
