  • Patent number: 10848018
    Abstract: A stator is provided. In this stator, a stator core comprises: an outer peripheral ring part formed in a ring shape; and multiple salient pole parts protruded from the outer peripheral ring part to an inner side in a radial direction of the stator. The outer peripheral ring part comprises outer peripheral parts in a same number as multiple salient pole parts. When an outer side face of the outer peripheral part in the radial direction is an outer peripheral face, both end side portions in the circumferential direction of the outer peripheral face of one of the outer peripheral parts are respectively formed to be a curved face part in a convex curved face shape which is a circular arc shape, curvature radii of the circular arc shapes are equal to each other and their curvature centers are common when viewed in an axial direction of the stator.

  • Patent number: 10148143
    Abstract: The motor of the invention includes the resin sealing member which covers a stator and a circuit board. The stator includes a stator core for winding a driving coil through an insulation member, and a terminal pin secured to the insulation member. The insulation member includes a press fitting portion for pressing and securing a portion of the terminal pin on a side of a second direction, whereas a portion of the terminal pin on a side of a first direction is soldered to the circuit board. A stopper portion is formed on a second direction end of the terminal pin. The stopper portion contacts a surface of the press fitting portion in the second direction to prevent the terminal pin from falling off in the first direction.

    Abstract: A stator is provided. In the stator, abutting surfaces are formed on both ends of each of outer peripheral parts constituting an outer peripheral ring section of a stator core, and the abutting surfaces of circumferentially adjoining outer peripheral parts are abutted together. Angles formed by first abutting surfaces, that is, an abutted surface which is formed along a joint located at one of the boundaries of the outer peripheral parts in the circumferential direction, and respective center lines of salient pole parts which connect with outer peripheral parts are smaller than an angle formed by each second abutted surface, that is, an abutted surface other than that of the first abutting surfaces, and a center line of a salient pole part which connects with the outer peripheral part on which this second abutted surface is formed.

  • Publication number: 20100295392
    Abstract: Provided is a motor which is thinned by improving the structure of a section for feeding a driving coil with power. In a motor, a stator is provided with substrate holding sections for holding a power feeding substrate in substantially vertical posture to a motor shaft line direction. On the power feeding substrate, land sections, to which coil terminals of driving coils are connected, are formed. Thus, a terminal block is not required, and a structure for firmly fixing a terminal pin to the terminal block for processing the coil terminal is not required.

  • Patent number: 7592725
    Abstract: A motor includes a motor case having an opening part and a stator core disposed in an inside of the motor case. The motor case may include a bottom face part, sidewall parts extended on the opening part side from an outer periphery of the bottom face part, and cutout parts formed by cutting the sidewall parts. Non-contact parts are formed in an outer peripheral edge of the stator core so that the stator core does not contact with an inner face of the motor case at the non-contact parts, i.e., with a burr formed at the cutout part of the motor case. Alternatively, the motor case may be formed as an outer stator core and the stator core may be formed as an inner stator core.
