Soft magnetic alloy, stepping motor for an electric timepiece, such as a Quartz clock, with a stator made of such a soft magnetic alloy

摘要

it is a weichmagnetische alloy for stepper motors for electric watches, especially for analog quartz watches is presented, which mainly consists of 60 ni 80 wt.% mn, 0.05 1.0 wt.%, 8.5 cr + 0.85 mo 15.0 wt.%.0 si equal to or less than 0.5 wt.%, 0 co 5.0 wt.%, 0 b 0.3 wt.%, and the rest fe and erschmelzungsbedingten and / or accidental contamination. this weichmagnetischen alloys show an induction of 0.30 b10 0.60 tesla at room temperature and a large-scale magnetic field h = 10 a / cm.the lower su00e4ttigungsinduktionen can with stepper motors with stator statorgeometrien einteiligem reality, compared with the state of the art in broader statorstege.
