1. By adopting a DC carbon-brush motor together with a precise electronic controlling board, JS-16V/30VP/32VP functions a stepless variable-spindle-speed change. It is easy to reach the required main spindle speed by lightly turning the speed controller without adjusting the belt. Thus, it is able to increase efficiency and reduce cost. And, it can also perform high torsion at a low spindle speed.
2. For economizing on packaging, JS-16V/30VP/32VP is packed in separate units and then put into a Styrofoam/ cardboard
box.
