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.

Abstract: An electric drive unit for driving devices connectable therewith includes at least one permanent magnets assisted reluctance motor and switching elements operatively associated to the at least one reluctance synchronous motor and designed to switch the connection of the stator windings between a first operating configuration and a second operating configuration, and vice versa, for variable torque and power delivery as a function of the rotation speed of the at least one reluctance synchronous motor.

Abstract: A synchronous reluctance motor comprises a stator (2) having at least one pair of poles and a plurality (ns) of grooves (3) for each pair of poles, a transverse-laminated rotor (5) with a plurality of disk-line sheet metal members (7, 7?, 7?, . . . ) of predetermined outside diameter (D), each having a plurality of adjacent slots (8, 8?, . . . ; 9, 9?, . . . ; 10, 10?, . . . ; 11, 11?, . . . ) and a central through hole (12) of predetermined inside diameter (d), each slot (8, 8?, . . . ; 9, 9?, . . . ; 10, 10?, . . . ; 11, 11?, . . . ) having a substantially curved elongate shape, symmetrical with respect to a radius, with end portions closed at the edge (13) of a corresponding sheet element (7, 7?, 7?, . . . ) to define corresponding ribs (14, 14?, 14?), which are adapted to be magnetically saturated to be equivalent to rotor slots. At least one first portion of the sheet elements (7, 7?, 7?, . . . ) has a ratio of the inside diameter (d) to the outside diameter (D) equal to or greater than 0.
