Patent ID: 10897170

Abstract:
The disclosure provides an electric machine that includes a stator with an electrical winding having electrically conductive bars arranged in grooves of the stator and each of which has a first cross-sectional area in the region of the grooves. The electric machine includes an inverter circuit for the controlled electrical energization of the winding. The inverter circuit is electrically connected to the winding, and/or the bars are electrically connected to one another, by a circuit board arrangement. The circuit board arrangement has passage bores with a diameter smaller than a maximum dimension of the first cross-sectional area, and one bar end of one of the bars is plugged through each passage bore. The plugged-through bar end has, in the region of the passage bore, a second cross-sectional area having a maximum dimension smaller than the diameter of the passage bore or equal to the diameter of the passage bore.
