Abstract
Description
Mpress=保持圧力又は射出圧力を形成するモーメント
Macc=慣性力
Mmot=(電気機械の)モータトルク
η=スピンドル(および/又は押出スクリュー)の効率
J=モータ、スクリューおよびスピンドルからなる結果として生じる総質量慣性モーメント
Kt=回転モーメント定数(Kt値)
I=モーメント発生電流
n=回転数
p=スピンドル勾配
Fs=推進力
Pscrew=保持圧力又は射出圧力
Rscrew=スクリュー半径
とする。ここで、
I) Mpress=(Mmot−Macc)×η
II) Mmot=Kt×I
III)Macc=J×dn/dt
が成り立つ。これから、IIおよびIIIをIに代入することにより、保持圧力又は射出圧力を発生するモーメントが求まる。
Mpress=(Kt×I−J×dn/dt)×η
Fs=Mpress×2n/p
Pscrew=Fs/(Rscrew×η)
