Abstract: Described is a method for optimizing a synchronous reluctance motor assisted by magnets (1), comprising the arrangement of a stator (2) provided with a number (t) of slots (3), the arrangement of a rotor (4) having an outer cylindrical surface (S.sub.e) of radius (r.sub.e), an inner cylindrical surface (S.sub.I) of radius (r.sub.I), a rotation axis (A) and a number (p) of pole pairs, realisation in the rotor (4) of a number (n) of slots (7) defining flow barriers (Bn) with axial extension for each pole of the motor (1), designed to house magnets (6) and definition of each barrier (B.sub.n) with peripheral profile in the form of a circular segment with convexity facing towards the axis (A) and with concentric radii of curvature (r.sub.nA, r.sub.nB) with common centre (C) arranged along a radial axis (X). The number (n) of barriers (B.sub.n) is greater than or equal to 3.

Abstract: A synchronous reluctance motor assisted by permanent magnets comprises a stator provided with stator windings, for generating a magnetic flux, which has a circular central seat to house a cylindrical shaped rotor suitable for being actuated in rotation about an axis of rotation, wherein the rotor comprises internal slots, for housing respective permanent magnets, and wherein the internal slots and the permanent magnets are curvilinear shaped in order to optimise the magnetic interaction between the rotor and the stator windings.
