Abstract
Description
ΔT=A*WJB+B*WVC+C*WGC …(1)
なお、ΔTは十分に時間が経過した後の上昇温度である。
(A)補正係数Cは、送電コイル部12と受電コイル部22との間のギャップGの二乗に反比例する。
(B)補正係数Cは、X軸方向の位置ずれ量(これを「Lx」とする)、及びY軸方向の位置ずれ量(これを「Ly」とする)に対して直線的に変化する。
C=(a*Lx+b*Ly+c)/G2 …(2)
Lx=Lg−Lv−L …(3)
こうして、X軸方向のずれ量Lxを求めることができる。
更に、上記の補正係数Cの実測値に基づいて、以下に示す(2)式の各係数a、b、cを求め、これらの係数a、b、cを用いて補正係数Cを演算してもよい。
C=(a*Lx+b*Ly+c)/G2 …(2)
このような演算方法を採用することにより、Lx、Ly、Gを演算式に代入するという極めて簡単な方法で補正係数Cを算出することが可能になる。
ΔT=A*WJB+B*WVC+C*WGC …(1)
Ta+ΔT+Tm≦(部品許容温度) …(5)
但し、Tmはマージンである。
