Abstract
PURPOSE: To highten frequency of rotation speed signal without enlarging toothed wheel sizes by differentiating number of tooth applied in rotating toothed wheel attached on rotating axis of phonomotors and etc., from teeth numbers of fixed toothed wheel confronting with rotating toothed wheel.
CONSTITUTION: On inner surface of rotating toothed wheel 32, made out from magnetic materials and fixed with rotating axis 31 and rotate, set teeth and also fixed toothed wheel 37, made out from magnetic materials and with teeth closely confronted with teeth of rotating toothed wheel, is fixed via permanent magnet 35 onto york plate 36. Set the numbers of teeth in a.m. rotating toothed wheel 32 in difference with that of fixed toothed wheel 37, for example set ratio of numbers for toothed wheel 32 to teeth of toothed wheel 37 in 9:10. By differentiating of teeth numbers like this, get bigger variation volume of magnetic flux and accordingly bigger signal and moreover, can get moderate in constituting accuracy in teeth making.
