    Abstract: PROBLEM TO BE SOLVED: To provide a slotless motor which can combine two or more unit coil bodies easily and correctly.
    SOLUTION: Two unit coil bodies facing each other are combined in a circular form with different inner diameters to constitute two or more circular coil bodies. Each circular coil body with a smaller inner diameter is inserted inside the circular coil body with a larger inner diameter sequentially out of two or more circular coil bodies to constitute a stator coil. Then, the respective sums of horizontal widths of two or more unit coil bodies of U phase, V phase and W phase are made equal, so the intensities of magnetic fields of the U phase, V phase and W phase are balanced and the stator can be manufactured correctly in response to the designer's intent, and the assembly process can also be simplified significantly.

    Abstract: PROBLEM TO BE SOLVED: To provide a PM stepping motor with a claw pole capable of reducing the outside diameter size .
    SOLUTION: A PM stepping is configured such that a first motor segment 300 and a second motor segment 400 are arranged in a symmetrical structure to form a module corresponding to a first pole teeth segment 520 and a second pole teeth segment 530 provided so as to face a main yoke member 500, respectively, which are incorporated so as to substantially divide into two halves the interior of a housing 100, into which a rotation shaft 200 is penetrated and supported in a rotatable state. The first motor segment 300 and the second motor segment 400 include magnet rotors 310, 410, and auxiliary yoke members 320, 420, and coil bobbins 340, 440, arranged on the same shaft so as to produce mutual electromagnetic force, respectively. With such a configuration, the coil bobbins are provided on the same shaft remaining to be separated from each other at a predetermined spacing, the outside diameter size of a motor can be further reduced, as compared with a structure in which the coil bobbins are arranged concentrically.
