PCB-Motoren für Kleinstantriebe in kleinen Lüfteranwendungen: eine Machbarkeitsstudie

This paper investigates the use of PCB motors for sub-fractional HP auxiliary fan drives. First, the basic idea of PCB motors as well as the main advantages and disadvantages are discussed, followed by the description of the design process for a PCB motor for a small automotive fan application. Three different stator designs have been implemented, each on a 4-layer PCB. Finally, the paper gives an overview of the measurements performed and the results obtained for the prototypes of the manufactured PCB motors and suggests design improvements.
