従つて切戻信号ｂがOpenになつても巻線に
保持電流を供給し続けるので保持力が高まる。 Therefore, even if the switch-back signal b becomes open, the holding current continues to be supplied to the winding, so that the holding force increases.
ここで保持電流は動作電流よりも小さくなるよ
うに抵抗値が定められている。 Here, the resistance value is determined so that the holding current is smaller than the operating current.
