位置定位器系統(tǒng)410的準(zhǔn)確度可以被定義為在金屬目標(biāo)408從初始位置掃描到結(jié)束位置期間的位置的測量與該掃描的預(yù)期理想曲線之間的差。該結(jié)果以相對于全標(biāo)度的百分比表示，如圖5所示。在圖5中，pos0是來自位置定位系統(tǒng)410的測量值，并且輸出擬合是理想曲線。pos0是從控制器402的寄存器測量的值，而fs是全標(biāo)度的值。例如，對于16比特寄存器，fs為2e16-1＝65535。圖6示出通過上式確定的用fnl％fs表示的誤差。目標(biāo)是以盡可能佳的準(zhǔn)確性(例如，％fs或更小)產(chǎn)生位置感測。如果使用試錯法設(shè)計(jì)pcb上的線圈設(shè)計(jì)，則可獲得的佳準(zhǔn)確性為％fs-3％fs。在pcb上形成的傳感器中，有兩個線圈和一個發(fā)射器線圈。測量位置的準(zhǔn)確性與線圈設(shè)計(jì)極為相關(guān)。pcb上的試錯線圈設(shè)計(jì)已經(jīng)經(jīng)驗(yàn)性地嘗試解決這些問題。然而，這種簡化但不準(zhǔn)確的方法只能考慮有限的問題。所有這些過程都無法得到成功的設(shè)計(jì)，這是因?yàn)檎麄€系統(tǒng)(線圈-目標(biāo)-跡線)要比容易解決的更復(fù)雜，并且，如果所得到的線圈設(shè)計(jì)將滿足期望的準(zhǔn)確性規(guī)范，則佳解決方案必須考慮更大量的參數(shù)。圖7a示出根據(jù)本發(fā)明的一些實(shí)施例的用于提供準(zhǔn)確的位置定位系統(tǒng)的印刷電路板上的線圈設(shè)計(jì)的算法700。</p><p> 余弦定向線圈110可以包括具有順時針定向的環(huán)路120和具有逆時針定向的第二環(huán)路122。圖1b示出由箭頭指示的可能的電動勢參考方向，該方向與由如圖1a所示的發(fā)射器線圈106產(chǎn)生的磁場一致。如本領(lǐng)域技術(shù)人員將認(rèn)識到的，可以以其他方式解釋所述定向。在圖1b所示的系統(tǒng)中，發(fā)射器線圈(tx)106被電路102(電路102可以是集成電路)激勵，以生成被示出為emf場108的可變電磁場(emf)。磁場108與線圈(rx)104耦合。如圖1b所示，如果將導(dǎo)電金屬目標(biāo)124放置在線圈104的上方，則會在金屬目標(biāo)124中生成渦電流。該渦電流生成新的電磁場，該電磁場理想情況下與場108相等并相反，從而抵消了在金屬目標(biāo)124正下方的線圈104中的場。線圈(rx)104捕獲由發(fā)射線圈106生成的可變emf場108和由金屬目標(biāo)124感應(yīng)的場，得到在線圈104的端子處生成的正弦電壓。在沒有金屬目標(biāo)124的情況下，在rx線圈104(在圖1b中被標(biāo)記為rxcos110和rxsin112)的端子處將沒有電壓。當(dāng)金屬目標(biāo)124相對于rx線圈104被放置在特定位置時，在被金屬目標(biāo)124覆蓋的區(qū)域上的合成電磁場理想地為零，因此在rx線圈104的端子處的電壓將具有不同的特性，這取決于金屬目標(biāo)124相對于接收線圈104的位置。傳感器線圈參數(shù)，無錫東英電子有限公司。</p><div

它與電感量L和交流電頻率f的關(guān)系為XL=2πfL品質(zhì)因素品質(zhì)因素Q是表示線圈質(zhì)量的一個物理量，Q為感抗XL與其等效的電阻的比值，即：Q=XL/R。它是指電感器在某一頻率的交流電壓下工作時，所呈現(xiàn)的感抗與其等效損耗電阻之比。電感器的Q值越高，其損耗越小，效率越高。線圈的Q值與導(dǎo)線的直流電阻，骨架的介質(zhì)損耗，屏蔽罩或鐵芯引起的損耗，高頻趨膚效應(yīng)的影響等因素有關(guān)。線圈的Q值通常為幾十到幾百。電感器品質(zhì)因數(shù)的高低與線圈導(dǎo)線的直流電阻、線圈骨架的介質(zhì)損耗及鐵心、屏蔽罩等引起的損耗等有關(guān)。分布電容任何電感線圈，其匝與匝之間、層與層之間，線圈與參考地之間，線圈與磁屏蔽罩間等都存在一定的電容，這些電容稱為電感線圈的分布電容。若將這些分布電容綜合在一起，就成為一個與電感線圈并聯(lián)的等效電容C。分布電容的存在使線圈的Q值減小，穩(wěn)定性變差，因而線圈的分布電容越小越好。額定電流額定電流是指電感器有正常工作時反允許通過的大電流值。若工作電流超過額定電流，則電感器就會因發(fā)熱而使性能參數(shù)發(fā)生改變，甚至還會因過流而燒毀。允許偏差允許偏差是指電感器上標(biāo)稱的電感量與實(shí)際電感的允許誤差值。一般用于振蕩或?yàn)V波等電路中的電感器要求精度較高。傳感器線圈優(yōu)勢，無錫東英電子有限公司。貴州增強(qiáng)傳感器線圈</p><p
