    摘要: A motor includes a rotating shaft, a rotor fixed to the rotating shaft and first and second stators facing each other on opposite axial sides of the rotor with a gap in between. Each of the first and second stators includes a back yoke, teeth circumferentially arranged on a gap side of a respective one of the back yokes and coils wound around the teeth. The back yoke of the first stator has a portion facing an end face of the rotating shaft, and the back yoke of the second stator has a shaft hole through which the rotating shaft passes. The thickness Ty1 of the back yoke of the first stator is set smaller than the thickness Ty12 of the back yoke of the second stator.

    摘要: A technique of employing a rotor having anti-saliency and being rotatable about a predetermined axis in an axial gap type motor is provided. A plurality of magnets are disposed annularly on a substrate with polarities being symmetric around a shaft hole. For instance, the magnets exhibit N pole and S pole, respectively, on the side of a stator (on this side of sheet of drawing). A plurality of magnetic members are disposed to extend perpendicularly to the direction of a rotation axis, and more specifically, between the magnets.

    摘要: A magnetic member with an annular outer periphery and an inner periphery includes first portions and second portions alternately disposed in its circumferential direction. The first portions and second portions are magnetically separated in the circumferential direction by gaps, which block magnetic fluxes from flowing in the circumferential direction between the first portion and second portion. The first portions respectively have holes extending almost in the circumferential direction. The gaps are provided at both ends of the holes in the circumferential direction between the outer periphery and inner periphery. An interior permanent magnet type rotor can be structured by inserting field magnets into the holes.

    摘要: Permanent magnets are in contact with first magnetic plates in a direction parallel to a rotation axis. The first magnetic plate includes first and second magnetic members and first and second non-magnetic members. The first magnetic member includes a pole center and is in contact with one of the permanent magnets. The first magnetic member, the first non-magnetic member, the second magnetic member and the second non-magnetic member are disposed in the stated order in a circumferential direction with the pole center and the rotation axis being as a starting point and a center, respectively. When Pn represents the number of pole pairs and i represents an odd number equal to or more than three, an angle θ1 defined by an end portion of the second non-magnetic member on the pole center side with respect to a pole gap is 0
