Abstract: A stator assembly for an electric machine, the stator assembly comprises a stator which extends between two end portions along a center axis of the stator assembly, corresponding to a rotational axis of the electric machine, the stator comprising a plurality of coolant fluid channels integrated in the stator, distributed in a circumferential direction around the stator and extending between the two end portions with openings at each end portion. The stator assembly further comprising a first coolant fluid distribution ring element provided at one of the end portions.

Abstract: An electrical machine is presented. The electrical machine comprises a rotor, a stator, a housing and a fluid circuit provided between an interior of the housing and the rotor axially along a longitudinal axis of the rotor. The fluid circuit is adapted to, by means of a fluid in the fluid circuit, exert a braking torque on the rotor.

Abstract: An electrical machine is provided. The electrical machine comprises a housing enclosing a rotor and a stator, wherein said stator comprises a stator core and end turns extending axially beyond the stator core. The electrical machine further comprises a first cooling system providing a flow of oil to the end turns of the stator, and a second cooling system having an axial end section overlapping the axial position of the end turns of the stator. The axial end section of the second cooling system is provided with one or more cooling fins.

Abstract: Arrangement for a power electronics unit in a hybrid vehicle power train, where all attachment points have a total thermal conductivity corresponding to less than 10 degrees temperature difference on a Kelvin-scale between electronics of said power electronics unit and the outside of said first transmission side for 5 kW of heat originating from one side of said attachment point. Arrangements including sound damping capabilities are disclosed. The arrangement can provide fewer parts and increased functionality of the power electronics unit.

Abstract: In an arrangement for a power electronics unit in a HEV, the HEV including a combustion engine, an electric motor/generator, a transmission, the power electronics unit is shaped as a plate. The plate is extended along a transmission side, the power electronics unit is fixed to the power train with a first attachment point. All attachment points have a total thermal conductivity corresponding to more than 10 degrees temperature difference on a Kelvin-scale between the power electronics unit and outside surface of said first transmission side and/or outside surface of the motor/generator for 5 kW of heat originating from one side of said attachment point. Embodiments also including sound damping capabilities are disclosed. The arrangement facilitates use of fewer parts and increased functionality.
