スピンドル回転の変速制御の電気的特性

抄録

A new speed-controller (KSC) was developed for spindles among the chase lift and during the build-up motion. It was improved through many practical tests in the spinning mill. The outline of the controller is described relating to the electric circuit of the progressive starter mechanism and speed controlling circuit for the build-up motion and among chase lift. Especially, a full detail of speed-control system using either direct-current motor or induction motor under alternative current is described.
