Patent number: 9312734Abstract: An armature of a linear motor is provided. The armature includes an armature core having a plurality of teeth arranged linearly and spaced at predetermined intervals, and a plurality of bobbins fitted onto adjacent teeth, each of the bobbins having flange parts, a winding being wound around the bobbin to form a coil. At least one of the flange parts of the bobbin is formed with a first protrusion and a second protrusion. An overlapped section is formed by the first and second protrusions of two adjacent bobbins contacting or overlapping with each other.Type: GrantFiled: February 25, 2013Date of Patent: April 12, 2016Assignee: KABUSHIKI KAISHA YASKAWA DENKIInventors: Yasuaki Kamiki, Seigou Nagamatsu

Patent number: 8415864Abstract: A rotating electrical machine includes a frame, a flange, a rotor, a stator, and a plurality of reinforcing bars. The frame has a plurality of side surfaces surrounding a space to form a substantially polygonal shape in a plane perpendicular to an axial direction of the frame. The side surfaces have a first side surface and a second side surface opposite to the first side surface. The frame has an end portion in the axial direction. The flange is provided at the end portion of the frame. The rotor is provided in the space and includes a shaft that is rotatably supported by the flange. The stator is provided in the space to be fixed to an inner section of the frame and to surround the rotor. The reinforcing bars intersect each other and are provided on the first side surface and the second side surface, respectively.Type: GrantFiled: January 17, 2011Date of Patent: April 9, 2013Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Yasuaki Kamiki, Hiroshi Tsumagari
