Abstract (en)
[origin: WO2015092672A2] A permanent magnet-assisted synchronous reluctance motor (1) comprises a stator (2) equipped with stator windings (4) defining a seat wherein a substantially cylindrical rotor (3) is positioned comprising a plurality of circular elements (5) adjacent to one another and one after the other, each of the circular elements (5) is equipped with a central axis of symmetry (12), the rotor (3) being rotary associated with respect to the stator (2) around the central axis of symmetry (12), the rotor (3) comprising seats (7), separated from one another by portions for conveying a magnetic flux (8), in which permanent magnets (9, 10, 11) are positioned in a number such as to determine a value of the phase difference between current and voltage for the permanent magnet- assisted synchronous reluctance motor (1) of cosφ comprised between 0.75 and 0.82.
