Abstract: Provided are: a geared motor with which a large torque can be obtained without an increase in size; and a method for producing said geared motor. In this geared motor (1), an output member (8) having a helical groove (83) formed in an outer circumferential section is provided between a first plate part (31) and a second plate part (32) of a frame (3), and the rotation of a motor pinion (55) is reduced in speed by a reduction gear mechanism (9) and is transmitted to a gear part (85) of the output member (8). In this geared motor (1): the output member (8) is arranged between the first plate part (31) and the second plate part (32); then, a first fixing shaft (35) is inserted from a through hole (37) in the second plate part (32) into a shaft hole (81) in the output member (8), and a first shaft end part (351) is fitted into a first fixing shaft support hole (36); and then, a second shaft end part (352) and the second plate part (32) are fixed.

Abstract: A stepping motor includes: a rotating shaft; a rotor fixed to the rotating shaft; a terminal unit disposed at a side of the rotor, and having an external power supply applied thereto; a coil coupled to the terminal unit; and an outer yoke disposed in circumferential directions around outsides of the coil and the rotor to form magnetic pole portions, and disposed in a circumferential direction around an inside of the coil to increase an area through which magnetic flux flows.

Abstract: An axial gap rotating machine rigidly fixing permanent magnets without reducing magnetic flux and having a high output has: a housing; a rotating shaft rotatably supported in the housing; two rotors having disks rotatably integral with the rotating shaft, and permanent magnets arranged concentrically in spaced relation to each other on at least one side of surfaces of the rotating disks in spaced relation to each other on at least one side of surfaces of the rotating disks in spaced relation to each other; and a stator arranged between the rotors, spaced from the rotors and fixed to the housing, the stator having a plurality of coils disposed concentrically around the rotating shaft spaced from each other; wherein magnetic flux generated from the permanent magnets of the rotors intermittently penetrates the interior of each of the coils as the shaft rotates, wherein the rotating disk has a concave portion in the surface facing the stator in which the permanent magnets are disposed so as to protrude.

Abstract: An axial gap coreless motor includes a stator including a stator yoke having a surface and being composed of a plurality of laminated layers of silicon steel sheets secured together, a wiring substrate having a surface and being disposed on the stator yoke surface, and a plurality of coreless coils annularly disposed on the wiring substrate surface; and a rotor including a rotor magnet having a plurality of circumferentially arranged magnetic poles, wherein the rotor is rotated relative to the stator such that the rotor magnet axially confronts the coreless coil over an air gap.

Abstract: A motor may include a rotor provided with a rotation shaft, a stator, a frame fixed to the stator and provided with a bearing part that rotatably supports an output side of the rotation shaft, and an urging member mounted on the bearing part for urging the rotation shaft. The bearing part may include a bearing, formed with a protruded part protruded from a flat plate part of the frame. The urging member may include a bottom face part provided with a spring part for urging the rotation shaft, a pair of side plate parts bent from side edge parts of the bottom face part, and a pair of hook parts bent on inner sides from the pair of the side plate parts to be engaged with the protruded part. The urging member is mounted on the bearing part such that the hook parts are engaged with the protruded part.
