Scientific and vacuum applications for DC motors are varied, an example being the Watt balance — a machine developed to compare masses with electrical values in a vacuum. The balance seeks to use Planck’s constant to redefine the kilogram in terms of voltage and current. The vacuum-capable motor has allowed scientists to build a 3-axis robot, providing the necessary mass movements for the experiment. maxon motor Australia Pty Ltd
