Publication number: 20070222332Abstract: A winding support for an electrical machine embodied as a lamination packet and has a plurality of pole teeth each having a pole foot about which a winding can be disposed. Beginning at the face ends of the lamination packet, the pole feet have an increasing width. The result is graduations in the tooth width, and thus the tooth cross section is “rounded” and hence smaller in circumference. The winding wire thus becomes shorter, and as a result the resistance drops.Type: ApplicationFiled: February 9, 2005Publication date: September 27, 2007Inventors: Gerald Roos, Harold Bitzer, Markus Rauschning
