摘要： In a stepping motor including two stators and a rotor having two magnets, three dimensional relations, specifically a relation of Lm/Ls, another relation of d/2Lm, and still another relation d/D, are optimally determined while satisfying their respective ranges: 0.35≦Lm/Ls≦0.45; 0.77≦d/2Lm≦1.10; and d/D≦0.45, where Lm is the axial dimension of the magnet, Ls is the axial dimension of the stator, d is the outer diameter of the magnet, and D is the outer diameter of the stator, whereby a space for accommodating a sufficient number of coil turns is secured maximally in the stator, and the inertia and the cogging torque of the rotor are reduced maximally, which leads to producing the highest possible torque at a high rotation speed range required.

摘要： In a motor comprising a stator assembly and a rotor assembly housed inside the stator assembly, a bobbin is structured to be oval-cylindrical in its radial cross section, rather than circular-cylindrical, such that a body section of the bobbin is composed of four continuous walls, two of which are formed of flat plates oriented perpendicular to the minor axis of the oval and disposed opposite to each other in parallel, and the other two of which are formed of outwardly arced plates oriented perpendicular to the flat walls and disposed opposite to each other in a symmetric manner. Pole teeth are provided only at portions corresponding to the arced walls to thereby reduce the dimension between the flat walls for downsizing while allowing an increased number of turns of a magnet wire wound around the bobbin.

摘要： The object of the present invention is to provide a rotary electric machine that provides bobbins with good assembling efficiency and allows no dislocation of the stator. A motor 2 comprises a case 4, a stator 6 secured inside the case 4, a rotor 10 formed into one piece with a rotating shaft 8. The stator 6 comprises stator yokes 32 and the stator yokes are secured in a radial manner in the case 4. Furthermore, resin 58 is filled in between the stator 6 and the case 4 with a space for the rotor being left. The stator yokes 32 comprise a salient pole 34, a bobbin 36 for holding the salient pole 34, and a magnetic wire 38 wound around the bobbin 36. A collar 39b of the bobbin 36 is formed so as to contact each other with notches 3 formed on two, upper and lower edge portions. Accordingly, combining two bobbins 36, 36 allows through-holes 5 penetrating the collar 39b thereof. This allows the stator to be firmly assembled, provides good assembling workability, and allows no dislocation owing to resin flowing when the resin is injected.
