The invention relates to a method for welding two welding parts () by means of a fillet weld (), wherein a first welding part (), with a bearing surface at least in an edge area of an edge that is to be welded by means of a fillet weld, is brought into contact with a bearing surface of a welding part () and the welding energy () is supplied in an energy supply area during the welding process, exclusive of a surface () of the first welding part facing away from the bearing surface, said energy supply area being located at a predetermined distance from the edge of the first welding part. The welding energy is supplied in a direction, whereby the direction component thereof points perpendicular to the course of the fillet weld that is to be produced in the direction of an inner area of the first welding part, forming a welding angle of less than 90&#xb0; with the contact plane of the bearing surfaces of the first and second welding parts. The welding energy is supplied until at least the energy supply area of the first welding part and a sufficient area of the second part, which is adjacent to the energy supply area of the first welding part, and also the material supply area located between the energy supply area and the edge of the first welding part are melted and fused together. The invention also relates to a welding part for carrying out said method and to an electric component with a printed conductor, which is welded to a cooling body of at least one power semiconductor element.

Method for welding two welding parts by means of a fillet weld and welding part with an inclined tapered edge area therefor

A method for winding a stator for a brushless direct current motor, which has a stator body () with a predetermined number of to be wound stator teeth () with the stator teeth () respectively being wound with two coils (W, W; W, W) which are magnetically coupled and which facilitate by supply of current with variable directional orientation the generation of opposite magnetic fields, whereby each of the two coils (W, W, W, W) comprises a predetermined number of in parallel arranged conductors. The stator teeth () are respectively wound simultaneously in several partial winding steps, with two conductors () or with an even number of 2n conductors, whereby one of the two conductors () or n conductor of the 2n conductors is allocated to the one coil and the other of the two conductors () or the other n conductor of the 2n conductors are allocated to the other coil and whereby a pre-determined number of partial winding steps is performed until the pre-determined number of conductors per coil (W, W; W, W) has been reached.
