In the present, unmanned aerial vehicles (UAV) has arisen more and more attention due to the high efficiency, ease and safety in completing complex missions [1][2].
An improved approach for predicting the armature reaction field in Permanent-Magnet AC (PMAC) machines is presented, and eddy current reaction is take into account. Winding configuration of PM machines could be various, such as concentric winding or lap winding, integral or fractional slot winding, distributed or concentrated winding, single-layer or double-layer winding. Starting with the field produced...
Recently more and more attention has been paid to the application of flux weakening of a permanent magnet synchronous machine (PMSM). In this paper, many rotor configurations of the PMSM that are suitable for flux weakening operation were reviewed. A new stator design with shunt teeth has been studied by magnetic circuit analysis and finite element analysis. The new design and the conventional design...
