摘要：

Slim pump for cooling devices play an important role for cooling the electronics apparatus. This paper develops an axial-flux internal rotor type motor for the low-profile vortex pump. The integrated motor-pump structure is composed of an internal permanent magnet ( PM) disc rotor and double-sided external coreless stators with windings piled up on the printed circuit board (PCB). The impeller is disposed on the periphery of the magnet and a fluid dynamic bearing (FDB) is set in the centre of the magnet to rotate relative to the centre shaft. A prototype of the axial-flux motor pump and drive circuit has been made and tested. Both simulated and experimental results show that the proposed motor would be an acceptable solution for the slim notebook (NB) applications.
