Abstract (en)

[origin: DE102006002900A1] Electric machine comprises a stand with a coil system (10) containing eighteen partial coils (11-28) placed in each two grooves (6). Each two of the partial coils form one of nine interlaced partial coil groups. The partial coils of each partial coil group are assigned to different coil strands (34, 35, 36). A non-wound tooth (30) is present between each neighboring partial coil groups. Preferred Features: A supply or cooling channel (31) is arranged within the non-wound teeth. The machine also has a rotor (3) with permanent magnets (5).
