Patent number: 11735986Abstract: A method for producing a stator for an electrical machine includes providing the stator including a ring-shaped stator body, from which a plurality of stator teeth arranged spaced apart along a circumferential direction of the stator body protrude radially to the inside. A space is thereby provided between two stator teeth adjacent to one another in the circumferential direction. Second, a first injection molding of two stator teeth adjacent to one another in the circumferential direction with a plastic is performed. Third, a stator winding is arranged in the space. Fourth, a second injection molding of the stator winding arranged in the space with the plastic is performed such that an air gap and/or an air trap between the stator teeth injection molded in the second step and the stator winding after the arrangement of the stator winding in the space in the third step, is filled with the plastic.Type: GrantFiled: November 19, 2019Date of Patent: August 22, 2023Assignee: Mahle International GmbHInventors: Roberto Almeida E Silva, Bernd Blankenbach, Terry Cox, Philip Grabherr, Niklas Kull, Tim Male, Peter Pisek, Peter Sever, Josef Sonntag, Martin Williams

Patent number: 11451103Abstract: An electrical machine includes a rotor that is rotatable about a rotation axis, and includes a stator having electrically conductive stator windings. The machine includes a cooling channel through for cooling the stator windings. The stator has teeth extending arranged at a distance from one another along a circumferential direction of the rotor, the stator teeth protruding inwardly and carrying the stator windings. An interspace is formed between two stator teeth which are adjacent in the circumferential direction. An interspace is arranged in an insulation body having outer walls composed of a plastic, which delimit a body interior, in which a winding zone and a channel zone are provided. A stator winding is arranged in the at least one winding zone of the insulation body and a cooling channel for a is arranged in the at least one channel zone of the insulation body.Type: GrantFiled: November 18, 2019Date of Patent: September 20, 2022Inventors: Roberto Almeida E Silva, Bernd Blankenbach, Terry Cox, Philip Grabherr, Niklas Kull, Tim Male, Peter Pisek, Peter Sever, Josef Sonntag, Martin Williams

Publication number: 20200156296Abstract: A method for producing a stator for an electrical machine may first include providing a stator having a ring-shaped stator body, from which a plurality of stator teeth arranged spaced apart from one another along a circumferential direction of the stator body, for accommodating stator windings, protrude, wherein a space, in each case, may be embodied between two stator teeth adjacent in the circumferential direction. The method then may include first injection molding at least two stator teeth, which are adjacent in the circumferential direction, with a plastic, arranging at least one stator winding in the space between the at least two stator teeth, and second injection molding the stator winding with the plastic, so that at least one of an air gap and an air trap formed between the at least two stator teeth first injection molded and the stator winding is filled with the plastic.Type: ApplicationFiled: November 17, 2019Publication date: May 21, 2020Inventors: Roberto Almeida E Silva, Bernd Blankenbach, Terry Cox, Philip Grabherr, Niklas Kull, Tim Male, Peter Pisek, Peter Sever, Josef Sonntag, Martin Williams
