摘要： In a method for producing a material layer with a recess, a first suspension containing a binder is applied through a first opening in a first template and a second suspension containing a binder and solid particles is applied through a second opening in a second template. The first opening in the first template is completely contained within the second opening in the second template such that the second suspension completely surrounds the first suspension to produce a green body. The green body containing the first and second suspensions is sintered such that the first suspension is evaporated to provide the recess and permanent cohesion of the solid particles in the second suspension is achieved.

摘要： A method of arranging windings in a parallel delta configuration in a stator assembly includes connecting a first lead of a first winding to a first terminal. The first terminal is electrically connected to a printed circuit board assembly (PCBA) located at a first axial end of the stator assembly. The method also includes wrapping the first winding about a first tooth of a lamination stack to form a first coil, extending the first winding about at least a portion of a circumference of the lamination stack at a second axial end of the stator assembly toward a second tooth located opposite the first tooth, connecting the first winding to a second terminal electrically connected to the PCBA, wrapping the first winding about the second tooth of the lamination stack to form a second coil, and connecting a second lead of the first winding to the first terminal.

摘要： A stator assembly (10) for an axial flux motor (100) with a rotation axis (100a). The stator assembly (10) has a stator receptacle portion (30) of a motor housing (20) of the axial flux motor (100), a stator (40) and a potting body (50). The stator receptacle portion (30) defines a disk-shaped contact face (32a) for receiving the stator. The stator (40) is disposed on the disk-shaped contact face (32a). The stator (40) is potted in the stator receptacle portion (30). The potting body (50) is connected to the stator receptacle portion (30) in a form-fitting manner in such a way that the stator (40) in the stator receptacle portion (30) is secured by the potting body (50) at least in the axial direction (2).
