The Phase Variator is the economical timing mechanism used to adjust the position of various machine components-even while running. Installed between the driven machine and the process which requires timing, the Phase Variator provides a full 360 degree range of position control.

In normal operation, with the control knob stationary, the Phase Variator operates as a 1:1 phase transmission with input and output shafts rotating in the same direction. When a rotation is applied to the control knob, a differential action occurs between the input and output shafts allowing a machine operator to synchronize a production process.

This simple, positive timing device is ideal for more efficient machine set-ups and changeovers. The Phase Variator is the low cost answer to the timing challenges facing today's machine designers.
