The 4-5 of working principle graph of inductive synchronized can see, medium either winding connects two winding of slide to change in order to hand in when excitation voltage, as a result of electromagnetism effect, corresponding inductive electromotive force arises necessarily on scale winding. The size of inductive electromotive force depends on slide is opposite the position at scale. Graph 4-6 gave out slide winding (slide) opposite at scale winding (scale) when be in different position, the metabolic circumstance of electromotive force of the reaction in scale winding. Dot of the A in the graph expresses slide winding and scale winding coincide, at this moment the inductive electromotive force in scale winding is the largest; If slide photograph is nodded from A to scale gradually towards the left (or right) parallel shift, inductive electromotive force is reduced gradually subsequently, just stagger in two winding the positional B of 4 pitch of 1 ／ is nodded, inductive electromotive force is decreased for 0; If continue to move again, move the C dot of 2 pitch of 1 ／ , inductive electromotive force turns into accordingly as identical as A position, but polarity is contrary, when the D that reachs 4 pitch of 3 ／ is nodded, inductive electromotive force turns into again 0; Ever since, moved a pitch reachs E point, the circumstance is nodded with A again identical, was equivalent to returning A dot again. Such, slide is in mobile in the process of a pitch, the inductive electromotive force of winding of inductive synchronized scale changed at cosine function approximately a cycle. If use mathematical formula to describe, setting is to be added in the excitation on slide either winding to hand in change the working principle of synchronized of induction of voltage graph 4-6 (4—12) by afore-mentioned reaching electromagnetism principle, the inductive electromotive force on scale winding is (4—13) coefficient of coupling of the K—— in type; The relatively mobile distance X that what —— mirrors is scale and slide, can express with next type: ／ of =(2π ／ 2)x=(π ) X (4—14) by type (4-14) and type (4-15) is knowable, the working principle of inductive synchronized and polar type rotate the working principle of transformer is same, want to measure metrical value only, can seek a role, get slide to be apart from X relative to what move at scale then. Bring to bear on when the two winding that go up to slide respectively when different excitation voltage, be like type (4-3) , (4-4) and type (4-6) , (4-7) place shows and, hand in according to the excitation that bring to bear on change of voltage signal different, inductive synchronized also divides type of the photograph that it is ancient bronze mirror and ancient bronze mirror type works two kinds means, its principle and 4 extremely type rotates transformer is identical, CNC Milling CNC Machining
