Moulding refers to a set of manufacturing techniques in which a mould, usually a cavity or a solid frame, is used to shape a liquid or pliable material into an object of the desired shape. The popularity of moulding comes from its effectiveness, scalability and versatility in terms of employed materials. Its relevance as a fabrication process is demonstrated by the extensive literature covering different...
For the flexible production of increased efficient electric traction drives, a new winding method in terms of the indirect needle winding has been developed. It is the aim to show the full potential of the new winding technique by the manufacturing of an improved motor winding, which consists of diamond coils with twisted litz wire. Adapted devices, in particular a winding template and a needle winding...
A continuously rising number of electric vehicle licensing is mentioned since the last few years in Germany. For a cost-efficient production of electrical engines in first-class quality and in sufficient quantity, it is indispensable to understand the process of coil winding. Thereby, the prediction of wire behavior is one of the key challenges. Therefore, a detailed model is built to investigate...
Slowly but steadily, more and more electric vehicles push onto the consumer market. For a cost efficient production of electrical engines, in first-class quality and in sufficient quantity, it is indispensable to understand the process of coil winding. Thereby the prediction of the wire behavior is one of the key challenges. Therefore, a detailed model is built to investigate wire behavior during...
State of the art needle winding technologies have one thing in common — a stiff, straight or bent winding needle. During the manufacturing process of electrical machines, the used enameled wires are exposed to deformations which decrease the insulation resistance against partial discharge and disruptive discharge. A reduced insulation resistance shortens the product lifecycle. The active controllable...
Due to the increased electrification of automobile powertrains, a strong market growth for electric drives is expected. Therefore the current manufacturing processes of powerful electric drives need to be modified for high volume production. The main idea for a new manufacturing process for a segmented stator was to integrate the wiring into the winding process in order to omit some production steps...
Progress in cloth simulation for computer animation and apparel design has led to a multitude of deformation models, each with its own way of relating geometry, deformation, and forces. As simulators improve, differences between these models become more important, but it is difficult to choose a model and a set of parameters to match a given real material simply by looking at simulation results. This...
