19. A method for producing a bond between a positive DC bar (4), a negative DC bar (5) and DC contact surfaces of a power semiconductor of power electronics in an electric machine, the method comprising the steps of:
-
one of soldering and applying a connection medium to a bond (6) of the positive DC bar (4), a bond (7) of the negative DC bar (5) and the DC contact surfaces of the power semiconductor (8);
supplying an initial current to the electric machine and the power electronics for a first time after assemblage of the electric machine and the power electronics, such that a bond is produced by heat generated on the DC contact surfaces due to an initially high ohmic resistance;
decreasing the ohmic resistance on the contact point such that the electric machine is prepared for regular operation. - View Dependent Claims (20)
