Abstract: A bobbin insulating and electric motor stator form an adjacent wire coil is made from a bobbin assembly including a first part and a second part, both formed of a dielectric thermal vacuum formable polymer. The first part includes a first flange and first tube extending integrally from the first flange. The second part includes a second flange and a second tube extending integrally from the second flange. The first and second tubes are sized and shaped so as to be engageable together to form an endless winding surface between the first and second flanges. The first and second parts are made with thermal vacuum techniques to be very thin. The thickness of the first and second parts ranges from 2 to about 25 mils, more desirably 2 to about 15 mils, still more desirably 2 to about 10 mils, and most desirably 2 to about 7 mils.
