Inhalt:
This paper concerns a 3D-printed air-gap respectively slotless winding for permanent magnet synchronous machines. Due to the substitution of conventional polymer-based insulation materials by ceramic and the extensive capabilities of three-dimensional design a wider field of application can be achieved. Especially the possibility of ceramic to withstand higher operating temperatures and its improved thermal conductivity compared to conventional plastic insulation systems allows the design of high temperature machines. Possible applications are auxiliary drives in high temperature environment and aerospace. This marks a break-through in advanced winding technology. To figure out the advantages and disadvantages the printed winding is compared with a conventional wire winding. Therefore, a machine equipped with both winding types is tested in passive and active mode.
