Abstract:
1. A DC motor comprising a cylindrical coil carrier ( 7 ; 17 ) comprising first wire guide elements ( 10 ) and second wire guide elements ( 12 ) for guiding a first winding wire ( 80 ; 180 ) and a second winding wire ( 81 ; 181 ) of an air-gap winding on an upper side end section ( 201 ) and a lower side end section ( 202 ), characterized in that the first winding wire ( 80 ; 180 ) and the second winding wire ( 81 ; 181 ) each comprise substantially rectangular winding segments ( 20 ; 120 ), wherein the substantially rectangular winding segments ( 20 ; 120 ) of said first winding wire ( 80 ; 180 ) and the substantially rectangular winding segments ( 20 ; 120 ) of said second winding wire ( 81 ; 181 ) are disposed overlapping on the cylindrical coil carrier ( 7 ; 17 ) and the first and second wire guide elements ( 10 , 12 ) are designed for guiding said first winding wire ( 80 ; 180 ) and said second winding wire ( 81 ; 181 ) past each other, wherein the second wire guide elements ( 12 ) are knobs disposed on the ends of the upper and lower side end sections ( 201 , 202 ), and wherein the first winding wire ( 180 ) is guided only along the knobs ( 12 ) disposed on the upper side end section ( 201 ) and the first wire guide elements on the lower side end section ( 202 ), and the second winding wire ( 181 ) is guided only along the knobs ( 12 ) disposed on the lower side end section ( 202 ) and the first wire guide elements on the upper side end section ( 201 ).
