An axial flux machine for a drive train of a purely electric or hybrid motor vehicle having an annular stator and two rotor elements which are mounted so as to be rotatable relative to the stator about a rotational axis. A first rotor element is arranged axially adjacent to a first end face of the stator and a second rotor element is arranged axially adjacent to a second end face of the stator. The stator has a plurality of stator cores that are distributed in a circumferential direction of a circular line extending about the axis of rotation and are designed in a wedge shape in the radial direction. At least one stator core has a plurality of radially extending sheet metal segments that are stacked on top of one another in the circumferential direction and are of plate-like design. All of the sheet metal segments (are surrounded on their two circumferential sides, that face away from one another in the circumferential direction, by a covering section made of a soft-magnetic composite material.

An electric motor including a stator between a first and second rotor. The stator and the rotors are mounted to non-rotating shaft. The stator includes a plurality of windings and the first and second rotors include a plurality of magnets on a side thereof facing the stator. An opening internal to the electric motor is to provide cables and cooling to the stator.

An axial flux machine is described. The machine has a stator comprising a stator housing enclosing a plurality of stator bars disposed circumferentially at intervals around an axis of the machine, and a rotor comprising a set of permanent magnets and mounted for rotation about the axis of the machine. The rotor is spaced apart from the stator along the axis of the machine to define a gap between the stator and rotor and in which magnetic flux in the machine is generally in an axial direction. The machine also comprises a hub assembly comprising a rotating hub and a mount separated by a bearing to permit the hub to rotate relative to the mount, the rotating hub comprising a hub flange and the mount comprising a mount flange, each of the flanges being spaced axially apart from one another. The machine further comprises a bulkhead for mounting the hub assembly and stator, wherein the bulkhead is mounted to the mount flange of the hub assembly and the stator housing is mounted to the bulkhead. The rotor comprises first and second rotors disposed either side of the stator, the first rotor being mounted to the hub flange and the second rotor being mounted only to the first rotor, the first and second rotors together forming a U-shaped rotor extending across and either side of the stator and being rotatable relative to the stator about the axis of the machine.

A is constructed such that upper and lower shafts, which are coaxial, are rotated in opposite directions using a single coil winding, simplifying the structure of the motor apparatus and reducing the numbers of sensors and controllers to be mounted thereon.

A hybrid electrical machine containing surface mounted magnets which includes a magnetically permeable cylindrically shaped stator assembly having at least one stator winding formed about a plurality of stator teeth, a rotor assembly concentrically disposed within the stator assembly, including a magnetically permeable rotor backiron, a rotational drive mechanism coupled to the rotor backiron, and a plurality of protruding rotor poles, each including a magnetically permeable pole support assembly, a winding provided around the pole support assembly, and a radially magnetized permanent magnet assembly disposed about the pole support assembly.
