    摘要: Es wird eine weichmagnetische Legierung für Schrittmotoren für elektrische Uhren, insbesondere für analoge Quarzuhren vorgestellt, die im wesentlichen aus 60
    0 ≤ Si ≤ 0,5 Gew.%, 0 ≤ Co ≤ 5,0 Gew.%, 0 ≤ B ≤ 0,3 Gew.%, Rest Fe sowie erschmelzungsbedingten und/oder zufälligen Verunreinigungen besteht. Diese weichmagnetischen Legierungen weisen eine Induktion von 0,30 ≤ B 10 ≤ 0,60 Tesla bei Raumtemperatur und einem angelegten Magnetfeld H = 10 A/cm auf. Durch die niedrigeren Sättigungsinduktionen lassen sich bei Schrittmotoren mit einteiligem Stator Statorgeometrien verwirklichen, die im Vergleich zum Stand der Technik breitere Statorstege aufweisen können.

    摘要: A wristwatch movement (1) has a Lavet stepping motor (18) directly driving a center wheel (8) attached to the minute hand (32). The frame plate (2) of the movement is of non-magnetic plastic material with recesses (37, 38) locating the pole shoes (20a, 21a) of two stator members (20, 21) of the stepping motor (18). An integral plastic cylindrical wall (22) extends from the recess (37, 38). The stepping motor rotor (35) is rotatably supported within the wall (22) by a journal at one end in the frame plate (2) and at the other end by a cap (23). The stator pole faces (20d, 21d) are accurately spaced from the rotor (35) by the wall (22) and held in place by deforming (24, 25, 26) plastic material against the stator pieces (20, 21) toward the wall (22).

    摘要: A magnet rotor in which rotation prevention and positional displacement (rattling, and misalignment of axes) between a magnet and a rotor body can be restricted, a movable magnet type-instrument with the magnet rotor, and a stepping motor with the magnet rotor. In the magnet rotor, projections (11) and recesses (12) arranged with predetermined intervals and formed in a substantially rectangular shape are provided on the inner wall of a hollow section of an annular magnet (10). Rising side wall sections (11A) defined by the projections (11) are radially directed with the position of the axis (G) of the magnet rotor (R) as the standard. In the rotor body (20), rotation prevention sections (21) for preventing relative rotation between the rotor body (20) and the annular magnet (10) are formed by placing a plastic material along the shapes of the projections (11) and the recesses (12).

    摘要: A stepping motor 10 comprises a rotor 3 of a permanent magnet 2 having multiple poles magnetized in the circumferential direction, and multiple stator yokes 5a and 5b disposed on the outer periphery of this rotor 3 to form a multiple-phase field magnet of multiple phases. Detent torque of the stepping motor is reduced either by reducing a cross-sectional area of a portion, which leads to a magnetic pole surface 51a of the stator yoke, to be less than an area of the magnetic pole surface 51a, or by disposing an intermediate magnetic substance 9 which is magnetically independent of the stator yokes 5a and 5b on both sides thereof. In addition, a stator yoke 5 is formed of two-divided members and both divided members 51 and 52 are connected to each other inside a winding bobbin 7 so as to increase the quality and the workability of assembly.

    摘要: A stator (1) comprises a first stator portion (1a) and a second stator portion (1b), which consist of high-permeability material and are united by welding with low-permeability or nonmagnetic connections (1c, 1d) interposed. The stator includes a hole (2) provided with a pair of recesses (5a, 5b), which establish an initial phase angle ( theta 1) and serve as means for setting the torque to hold the rotor (3) magnetically. A field coil (7) is connected magnetically between the terminals of the stator (1) to form a two-pole stepper motor for a timepiece.
