Abstract: A stator for an electric machine includes a core and a multi-phase winding arrangement positioned on the core. Each phase of the winding arrangement includes a plurality of parallel paths defining a plurality of poles for the electric machine. Each parallel path includes a plurality of coils positioned on the core, each coil defined by coil legs and end turns. The coil legs include left legs and right legs extending through the slots of the core. The left legs and right legs of each coil are connected by first end turns at one end of the core and second end turns at an opposite end of the core. Each pole of the electric machine is associated with a pole slot set comprised of multiple slots on the stator core. For each pole slot set, legs for each parallel path extend through one of the slots of said pole slot set.

Abstract: A rotor assembly includes a shaft defining a lubricant inlet channel for receiving a lubricant and a lamination stack. The lamination stack is rotatably coupled to the shaft, extends between first and second lamination stack ends, and defines a lubricant cooling channel in fluid communication with the lubricant inlet channel. The rotor assembly also includes a first end cap adjacent to the first lamination stack end and a second end cap adjacent to the second lamination stack end. One of the first end cap and the second end cap defines an end cap inlet at a first radial distance from the shaft, a lubricant outlet channel defined to extend at least partially radially inward toward the shaft, and an end cap outlet at a second radial distance from the shaft which is less than the first radial distance for expelling the lubricant.

Abstract: Disclosed is a turbine arrangement for a supercharging device. The turbine arrangement comprises a turbine housing, a turbine wheel and a guide device. The turbine housing defines a turbine spiral and a turbine outlet. The turbine wheel is arranged in the turbine housing between the turbine spiral and the turbine outlet. The guide device comprises a carrier ring and multiple guide blades. The guide blades are arranged on the carrier ring fixedly in a predetermined orientation. The guide device is arranged in an inflow channel between the turbine spiral and the turbine wheel such that, during operation, fluids are conducted from the turbine spiral through the inflow channel over the guide blades onto the turbine wheel.

Abstract: Disclosed is an electric motor having a stator, a rotor surrounding the stator, a shaft connected to the rotor in a rotationally fixed manner, and a housing that surrounds the rotor and the stator. The shaft has a first end arranged in the housing and a second end projecting out of the housing. The rotor has a back iron ring and permanent magnets attached to the inside of the back iron ring. The rotor has a carrier via which the back iron ring is connected to the shaft and through which the shaft projects, and the carrier is attached to the shaft between the second end of the shaft and bearings. The bearings include a floating bearing and a fixed bearing.

Abstract: An electric motor is described, with a stator, a rotor surrounding the stator, a shaft connected to the rotor in a rotationally fixed manner, a first housing component and a second housing component, which together enclose a motor compartment in which the rotor and the stator are arranged, wherein a first end of the shaft is arranged in the motor compartment, and a second end of the shaft protrudes from an opening of the second housing component. It is envisaged that the first housing component, together with a third housing component, encloses an electronics compartment in which control electronics are arranged, wherein a wall of the first housing component separates the motor compartment from the electronics compartment, and the control electronics have a circuit board whose board plane faces the said wall.

Abstract: A stator arrangement for an electric machine has a stator and an interconnection module. The stator includes a stator core on which a stator winding is arranged. The interconnection module electrically interconnects winding wire ends of the stator winding. The interconnection module is positioned on the stator on an end side. The interconnection module includes integral electrical terminal conductors which are embedded at least partially in a body of an electrically insulating material. The terminal conductors each form a terminal contact to which an external power supply and/or control of the stator arrangement can be connected, and a winding contact which is electrically conductively connected to a winding wire end.

Abstract: A stator arrangement (10) for a radial flux motor (100) having an axis of rotation (100a). The stator arrangement (10) comprises a stator housing (20), a stator (40) and an encapsulation body (50). The stator housing (20) defines a circumferential portion (30) for receiving the stator. The stator (40) is arranged on the circumferential portion (30). Furthermore, the stator (40) is encapsulated in the stator housing (20), wherein the encapsulation body (50) is form-fittingly connected to the stator housing (20) in such a manner that the stator (40) is secured at least in the axial direction (2) in the stator housing (20) by the encapsulation body (50).
