摘要： A small-sized and inexpensive electric motor in which connection of a stator coil is easy, the connecting portion occupies a small space, and stable torque characteristics are obtained by making electric resistance uniform. A coil bobbin is mounted on a magnetic pole of a stator core, and a stator coil is fitted. A lead wire is led to an external diameter side of one end of the stator core. A connecting conductor holder with a common coil-connecting conductor, connecting conductors for each phase and a through hole is mounted on an end of a coil bobbin. The common coil-connecting conductor has connecting terminals projecting in radial directions, and the connecting conductors for each phase have such a cross-sectional area as to equalize electric resistance of each phase after connecting the stator coil. The through hole is formed to allow a bearing-housing portion to be inserted.

摘要： An armature of a linear motor includes a plurality of first magnetic teeth and a plurality of second magnetic teeth, each of the magnetic teeth being formed by laminating multiple tooth elements made of electromagnetic steel sheets. The first magnetic teeth are arranged side by side in a linear form while the second magnetic teeth are located one each between the successive first magnetic teeth. Each of the second magnetic teeth interconnects the two adjacent first magnetic teeth located on both sides.

摘要： In a rotary electric machine laminated core, a rotating shaft portion is disposed closer to an outer circumferential surface than an inner circumferential surface of a back yoke portion. A notch portion is disposed on at least one of first and second end portions of the back yoke portion so as to form a gap between a vicinity of the rotating shaft portion of a projecting portion and a recess portion when core segments are arranged in an annular shape or a circular arc shape. The first end portion and the second end portion of the back yoke portion are configured such that a predetermined gap that connects from the outer circumferential side to the inner circumferential side is formed between adjacent projecting portions and recess portions when the core segments are expanded rectilinearly such that magnetic pole tooth portions are parallel to each other.
