Abstract
An electric machine, comprising: a housing enclosing an inner space, a stator and a rotor disposed in the inner space, an axis of rotation of the rotor defining an axial direction. The housing comprises an end wall extending transverse to the axial direction and closing the inner space in the axial direction. A separator element disposed in between the stator and the end wall along the axial direction, and the separator element delimiting a volume within the inner space for receiving an electrical conductor within said volume.

An electric machine, comprising:
- a housing enclosing an inner space which is hollow,
- a stator and a rotor disposed in the inner space, an axis of rotation of the rotor defining an axial direction, wherein the housing comprises an end wall extending transverse to the axial direction and closing the inner space in the axial direction and a longitudinal wall, and
- a separator element disposed in the inner space in between the stator and the end wall along the axial direction, the separator element forming a volume which is hollow and delimited by the end wall, the longitudinal wall, a first separator portion extending radially from the longitudinal wall toward the rotor, and a second separator portion extending from the end wall toward the stator, and wherein the separator element is shaped to separate the volume from the rotor, and
- an electrical conductor passing from the stator through the inner space, through a hole in the separator element, and into the volume.
A method of assembling the electric machine, the method comprising:
- disposing a separator element inside an inner space formed by an end wall and a longitudinal wall of a housing, the separator element forming a volume within the inner space, the volume delimited by the end wall, the longitudinal wall, a first separator portion extending radially from the longitudinal wall, and a second separator portion extending from the end wall;
- disposing at least a stator inside the inner space;
- passing an electrical conductor electrically connected to the stator through a hole of the separator element, into said volume, and out of an opening in the housing;
- connecting the electrical conductor positioned outside of the housing with a second electrical conductor;
- and
- passing the electrical conductor and a first portion of the second electrical conductor through the opening in the housing back into the volume.
