Abstract
An electrical machine for use in an aircraft, including a rotor. The rotor includes a plurality of rotor poles, and a stator including a plurality of phases. Each respective phase occupies at least one elementary block and the at least one elementary block of each phase includes a set of conductors of the respective phase wound around a plurality of slots of the respective elementary block in a concentrated winding configuration. A mechanical shift angle between the respective concentrated windings of each pair of adjacent elementary blocks is greater than a rotor pole pitch. The rotor pole pitch is an angle between adjacent poles of the rotor.
