摘要： A component for an electric machine includes a flat region in which an electric line runs when the component is integrated into the electric machine and which includes a sharp-edged structure. A polymer layer adheres to the flat region without further aid such as to mask the sharp-edged structure and thereby protect from damage the electric line on the flat region. The polymer layer is made of cured plastic adhesive and jetted onto the flat region in the form of threads, such that the threads are spin-coated on top of one another in the form of overlapping loops and form a network structure which spans the sharp-edged structure.

摘要： A brushless motor includes a motor body, a bracket, and a power supply structure for supplying power to the motor body through a through hole in the bracket. The motor body includes a stator having a core with teeth and a coil formed of a winding wound around the teeth. The power supply structure includes, for each phase, a winding pair including a first lead portion and a second lead portion of the winding, a guide part that guides the winding pair, and a connector part where the lead portions are electrically connected. The winding pair includes a first portion guided by the ide part and a second portion formed by bending the winding pair at an axially outer end of the first portion along a surface of the bracket. The first portion passes through the through hole in the axial direction. The second portion extends to the connector part.
