Stator bar insulation stripping machine and method

摘要

A machine is provided for stripping the ground wall insulation from a stator bar quickly and in such a manner that the copper strands will not be damaged. The apparatus of the invention includes a power driven cutting tool for milling or routing the insulation from a portion of the insulated bar, a sensing device for detecting the location of the copper strands and a height adjustment assembly for determining a disposition of the bar with respect to the cutting tool. In an exemplary embodiment, the height adjustment assembly is adjusted in accordance with the location of the copper strands as detected by the sensing device to substantially prevent the cutting tool from making damaging contact with the copper strands.
