Abstract: An electric motor for a motor vehicle includes a motor housing and a stator which is received in the motor housing and has a phase connection accommodated in a holding element. A housing floor of the motor housing has a feed-through opening. The phase connection and the holding element project through the feed-through opening for anti-torsion protection of the stator. A motor housing for such an electric motor is also provided.

Abstract: A stator of an electric motor has a number of radially directed stator teeth, onto each of which an insulating coil carrier for a coil of a multiphase rotating field winding is or can be placed. The stator teeth are connected to one another on the outer circumference on a yoke side, forming stator grooves. On the inner circumference, on a pole shoe side, a groove gap is respectively formed between adjacent stator teeth. Stiffening is provided on the inner circumference on the pole shoe side of the stator teeth, in the form of a stiffening element that projects into the or each groove gap.

Abstract: The invention relates to a method for producing a welding assembly (2, 8), in particular a housing of an electrical machine (1). A first, cold-formed joining partner (2), which is formed from a cold-formable first aluminium alloy having a low silicon content, and a second joining partner (8) formed from a second aluminium alloy having an increased silicon content as compared to the first aluminium alloy are provided. Said joining partners are joined by means of laser beam welding. The silicon content of the second aluminium alloy is increased relative to the first aluminium alloy in such a way that a silicon content of at least approximately 3% is provided in a welding zone (74) between the first and the second joining partner (2, 8).
