The yoke is assembled as an integrated yoke by inserting the straight portion into the through hole, and fixing the straight portion to the arcuate portion as another member.

Abstract: A coil wound body may include a coil bobbin around which a coil wire is wound. The coil bobbin may include a wound part around which the coil wire is wound, a terminal block part, a circuit board receiving face which is provided on the terminal block part and on which a wiring circuit board is disposed, and pin-shaped terminals. The coil bobbin is provided with a coil wire leading-out path reaching to root portions of the pin-shaped terminals from the wound part through an inner side of the circuit board receiving face. The coil wire are led out to the pin-shaped terminals by passing through the coil wire leading-out path without passing through a position overlapping with the outer side of the circuit board receiving face. The coil wound body is preferably applied to a motor.

Abstract: Disclosed are a step motor and a manufacturing method thereof. The step motor includes a stator having a bobbin in which a coil is received to generate a magnetic field when power is supplied, and a yoke having a plurality of yoke teeth engaged with the bobbin, a casing covering and protecting the stator, and a rotor inserted into an inner diameter part of the stator and having magnets on a circumference of a rotary shaft, so as to generate rotary force, wherein a bearing is installed to an end of the rotary shaft to support the rotor, and an elastic member is assembled to the bearing to force the end of the rotary shaft inwards in a motor assembly composed of the stator and rotor.

Abstract: The invention provides a motor including a terminal block that is insert molded into a core, so as to increase the strength to support the terminal block. A stator has paired inner cores configured by two inner cores facing back to back and each having a disk part and pole teeth. Each of the disk parts is provided with a terminal block holding part. The terminal block is connected with the terminal block holding parts via a resin connection part that is insert molded. The terminal block holding parts are provided with recesses configured by cutouts in portions to face the terminal block, respectively. The resin connection part has a thickness increased by filling the recesses so as to increase the strength at a connection portion thereof. The cutouts in the terminal block holding parts facing back to back are offset with respect to a radial line, terminal block facing ends are generally spaced apart from the terminal block by a constant distance. Therefore, the terminal block is prevented from being unstable.

Abstract: In a small diameter stepping motor including two stator units each including a bobbin formed of an insulating material, each bobbin includes: a circular hollow cylinder portion having a winding; two flanges disposed respectively at the both ends of the cylinder portion; and a terminal structure disposed at one of the two flanges and including two terminal blocks and a pair of electrical contact members at which the lead-out lines of the winding are terminated, wherein the two terminal blocks are circumferentially shifted in position from each other with respect to the cylinder portion axis extend axially outwardly, and the terminal blocks of one bobbin intermesh with the terminal blocks of the other bobbin such that the terminal blocks of the one bobbin overhang a part of the winding wound on the other bobbin and vice versa when the two stator units are coupled to each other.

Abstract: A coil member such as a coil bobbin may include a cylindrical drum part around which a coil is to be wound in a circular shape. The cylindrical drum part is formed by two molding dies and a flat face part is formed on an outer peripheral face of the cylindrical drum part so that a space part is formed between an innermost circumferential face of the coil to be wound and the flat face part. The flat face part is formed so that the two molding dies are separated without pressing the outer peripheral face of the cylindrical drum part, and a joining part on the drum part which is formed by the two molding dies is located on the flat face part. The coil member may be only a coil bobbin, a coil bobbin with a terminal part, or a coil bobbin which is integrated with a stator core.

Abstract: Provided are a stator for an aspiration motor, an aspiration motor and an in-car sensor using the same, in which a bobbin is integrally formed with a stator, to thus use an inexpensive insulation wire and enhance a productivity and lower an inferiority using an insert-molding technology. The stator for the aspiration motor includes a stator support plate, a support boss which is vertically extended from the central portion of the stator support plate, a bobbin which is bent and formed on the lateral surface of the support boss, and which is separated from the upper side surface of the stator support plate, to thereby provide a space, and a stator coil which is formed by making a wire wound in the space provided by the bobbin.

Abstract: A driving apparatus that can be made compact, without increasing the number of component parts and decreasing diameters of a rotating shaft and bearings. When a first unit assembled from a first stator and a first bobbin is coupled to a second unit assembled from a second stator and a second bobbin, engaging portions of the first bobbin are caused by a first switching member to shift from a disengaged state from the first stator to an engaged state with the first stator, and a second switching member, and engaging portions of the second bobbin are caused by a second switching member to shift from a disengaged state from the second stator to an engaged state with the second stator.
