Problems solved by technology

Due to these loads, cracks can appear in the casting material, which on the one hand at least weaken the mechanical stability of the winding head, and on the other hand also limit (if not significantly reduce) at least the thermal conductivity of the casting material, which Thermal conductivity is one of the important properties of casting materials

Description

technical field [0001] The invention relates to a stator for a vehicle electric machine, the stator having a winding head, wherein the winding head has a plurality of windings and the windings of the winding head are cast with a casting compound. The invention also relates to an electric machine for a vehicle with a stator and a rotor and a vehicle with an electric machine. Background technique [0002] In modern technology, especially also in modern vehicle technology, electric machines are widely used to convert electrical energy into mechanical energy and vice versa. The waste heat generated during this conversion of energy must be dissipated as efficiently as possible in order to prevent overheating of the electric machine on the one hand and to increase the overall efficiency of the electric machine during operation on the other hand. The winding ends of the stator of such electric machines are particularly critical areas. In this case, the electrical conductors gener...
