Patent number: 11831216Abstract: A linear motor system includes: a mover including permanent magnets arranged in a traveling direction in a plane parallel to a plane formed by the traveling direction and a vertical direction; and a stator including an armature including an iron core in which projections around which windings are wound are arranged in the traveling direction, the armature being disposed to face the permanent magnets of the mover. The mover includes a mover body including a first main roller engaged with a first traveling surface disposed on the stator, a placing table on which a conveyance object is placed, and a sub-roller engaged with a second traveling surface disposed on an upper surface of the stator. The first main roller supports a magnetic attraction force generated between the stator and the mover, and the sub-roller supports a force in a direction opposite the magnetic attraction force acting on the mover.Type: GrantFiled: August 27, 2019Date of Patent: November 28, 2023Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Fumihiko Nakagome, Masaoki Iwase, Kazuhiko Fukushima, Hiroshi Wakayama, Takahiko Murakami

Publication number: 20230194254Abstract: A wear amount estimation device estimates the amount of wear on mover wheels of a conveying device having a mover movable by a wheel-type guide mechanism, the mover being driven and controlled by a linear motor. The wear amount estimation device includes: a data acquisition unit that acquires, as estimation data, information on a control current flowing through the linear motor in order to drive and control the mover and information on a controlled position or speed of the driven mover; a storage unit that stores a wear amount estimation model for estimating the amount of wear; and a calculation unit that estimates the amount of wear by inputting the estimation data to the wear amount estimation model.Type: ApplicationFiled: December 25, 2020Publication date: June 22, 2023Applicant: Mitsubishi Electric CorporationInventors: Takahiko MURAKAMI, Hiroshi WAKAYAMA, Shin SAKAI, Takuma NAKAMURA

Patent number: 10050508Abstract: An armature has a plurality of armature cores arranged in a line in a first direction, coils wound on an area of the armature cores in a second direction, a carrier provided with a space in which to dispose the coils left in a third direction orthogonal to the first direction and the second direction with respect to the armature cores, and at least one mounting member to fix the armature cores and the carrier. The armature cores are fixed to the mounting member by first bolts, and the carrier is fixed to the mounting member by second bolts. The at least one mounting member, the first bolts, and the second bolts are disposed in positions not overlapping the coils when viewed from the third direction.Type: GrantFiled: May 27, 2015Date of Patent: August 14, 2018Assignee: Mitsubishi Electric CorporationInventors: Hiroshi Wakayama, Ryutaro Inagaki, Shinichi Yamaguchi, Kazumasa Ito, Kenta Motoyoshi

Publication number: 20180076675Abstract: Two teeth on which windings are wound, and a teeth connecting portion disposed between the two teeth, connecting the teeth together, and having a mounting hole formed therein, are arranged in a line in a second direction, which is an arrangement direction. The teeth connecting portion has a support that supports the windings. The support has projections protruding from both end portions in the second direction of the teeth connecting portion to both sides in a first direction which is a width direction, and spaces formed between the projections in the second direction.Type: ApplicationFiled: May 26, 2015Publication date: March 15, 2018Applicant: Mitsubishi Electric CorporationInventors: Hiroshi WAKAYAMA, Eigo TOTOKI, Shinichi YAMAGUCHI, Kenta MOTOYOSHI, Yosuke TAKAISHI

Patent number: 9594001Abstract: An ultrasonic testing device includes: a liquid tank that stores the liquid into which the differential casing is to be immersed; a workpiece holder that holds the differential casing and immerses the differential casing into the liquid in the liquid tank; an ultrasonic probe that conducts an ultrasonic testing of the welded part of the differential casing by irradiating the ultrasonic wave to the welded part and receiving a reflected wave; an image processing module that generates an ultrasonic image based on the reflected wave received by the ultrasonic probe; and a replacer that replaces gas inside an air gap formed at a weld toe of the welded part with test liquid. The replacer replaces the gas inside the air gap by the test liquid before the ultrasonic probe irradiates the ultrasonic wave.Type: GrantFiled: September 10, 2015Date of Patent: March 14, 2017Assignee: FUJI JUKOGYO KABUSHIKI KAISHAInventor: Hiroshi Wakayama
