  • Main element of an electric machine
    Patent number: 9667103
    Abstract: The invention relates to a main element (400) of an electric machine. Said main element (400) comprises several winding strands (100, 200, 300) with electric coils (101, 102, 201, 202, 301, 302) which interconnected so as to be electrically conductive and a winding core (K) which comprises first grooves (1, 3, 4, 6, 7, 9), through which the precisely one coil (101, 102, 201, 202, 301, 302) runs, and second grooves (2, 5, 8), through which precisely two different coils (101, 102, 201, 202, 301, 302) run. Each coil (101, 102, 201, 202, 301, 302) of each winding strand (100, 200, 300) is either a first coil (101, 201, 301) which runs through two first grooves (1, 3, 4, 6, 7, 9), or a second coil (102, 202, 302) which runs through two second grooves (2, 5, 8).
