Patent number: 11777352Abstract: An electrical machine for a vehicle may include a rotor, a stator, a coolant distributor chamber and a coolant collector chamber. The rotor may be configured to be rotated about an axis of rotation defining an axial direction of the electrical machine. The stator may include a plurality of stator windings. The coolant collector chamber may be axially arranged at a distance from the coolant distributor chamber. The coolant distributor chamber may be configured to communicate fluidically with the coolant collector chamber by at least one cooling channel through which a coolant can flow. At least one of the stator windings may be embedded in at least one plastic mass consisting of an electrically insulating plastic for thermal coupling to the coolant. At least one of the coolant distributor chamber and the coolant collector chamber may be arranged at least partially in the at least one plastic mass.Type: GrantFiled: May 18, 2018Date of Patent: October 3, 2023Inventors: Mirko Hoerz, Hans-Ulrich Steurer, Josef Sonntag, Stojan Markic, Andrej Licen, Aleks Medvescek, Peter Sever, Philip Grabherr

Patent number: 11728703Abstract: An electric machine includes a rotor, rotatable about an axis of rotation defining an axial direction, and a stator having stator windings, a coolant distribution chamber and a coolant collection chamber arranged axially at a distance thereto. The coolant distribution chamber fluidically communicates with the coolant collection chamber with a cooling channel through which a coolant can flow. The cooling channel and the stator winding are embedded in a plastic mass made of a plastic for thermal coupling to the coolant. The stator has stator teeth extending along the axial direction and spaced apart from one another along a circumferential direction and carrying the stator windings. The plastic mass is arranged together with the cooling channel and the stator winding in an intermediate space formed between two stator teeth arranged adjacent in the circumferential direction and sections of cooling channel are configured as a tube body within the intermediate space.Type: GrantFiled: June 3, 2020Date of Patent: August 15, 2023Assignee: Mahle International GmbHInventors: Philip Grabherr, Mirko Hoerz, Andrej Licen, Stojan Markic, Aleks Medvescek, Peter Sever, Josef Sonntag, Hans-Ulrich Steurer
