Patent number: 11050329Abstract: A mother substrate that enables winding cores to be obtained in a manner in which the mother substrate is divided along x-direction division lines and y-direction division lines is prepared. Subsequently, x-direction division grooves are formed along the x-direction division lines on a first main surface of the mother substrate, y-direction division grooves are formed along the y-direction division lines on the first main surface, and shallow bottom surface exposure grooves, for exposing surfaces that are to be core portion bottom surfaces, are formed on the first main surface. The mother substrate is divided by performing a flattening process on a second main surface of the mother substrate that is opposite the first main surface until the second main surface reaches the x-direction division grooves and the y-direction division grooves to obtain the winding cores that are separated from each other.Type: GrantFiled: December 3, 2018Date of Patent: June 29, 2021Assignee: Murata Manufacturing Co., Ltd.Inventor: Eiji Yamauchi

Patent number: 11038395Abstract: A winding-start receiving groove in which a winding-start lead wire of a field coil is received is formed in an inner surface of a flange of an insulation bobbin. A holder is disposed on the flange and located on a radially outer side of the winding-start receiving groove. The holder is formed with a holder groove located on an extension line of the winding-start receiving groove and extending at an angle relative to a radial direction of the insulation bobbin. The winding-start lead wire of the field coil is received in the winding-start receiving groove and the holder groove and held by the holder. This makes it possible to obtain a rotor of a rotary electrical machine with a simplified configuration at low cost not only to improve winding workability but also to enhance electrical reliability and durability.Type: GrantFiled: May 31, 2016Date of Patent: June 15, 2021Assignee: Mitsubishi Electric CorporationInventors: Shintaro Shimizu, Kenji Maekawa, Toru Ishikawa, Yoshiro Imazawa
