  • Abstract


    The current paper describes the design and development of a pc-controlled three axis traverse system that aims to serve extensive velocity and temperature measurements into the drying chamber of a laboratory scale convective dryer. The traversing gear design has been conducted based on the convective dryers specific experimental requirements and limitations. The fabricated traversing gear uses a trapezoidal lead screw-nut assembly supported by linear ball bearings, coupled with bipolar stepper motors for positioning in three dimensional spaces. A custom drive system solution was selected for achieving accurate motor control, paired with computer software developed using the LabVIEW graphical programming environment. The functionality of the traversing system was experimentally verified by testing mechanical and electronic assemblies, but also by determining the per axis positioning error.
