ELECTRIC GENERATOR

Title:

ELECTRIC GENERATOR

Document Type and Number:

WIPO Patent Application WO/2012/073206

Kind Code:

A3

Abstract:

An electric energy generator comprises a driving shaft (3) designed to be coupled to an external energy source having a predetermined torque, a synchronous reluctance rotating electric machine (7) having a stator (8) and a transverse-laminated rotor (9), and a driven shaft (6) operatively coupled to the drive shaft (3) for generating electric energy with a predetermined torque ripple amplitude, electric connection means (13) for injecting the electric energy so generated into the net (R), control means (14) designed to adjusting electrical and dynamic parameters of the electric machine (7). The stator (8) has an even number (ns) of longitudinal grooves (15) for each pair of poles and the rotor (9) has a plurality of adjacent slots (16) defining an even number (nr) of magnetically equivalent slots. The number (ns) of grooves (15) is different from the number (nr) of equivalent slots multiplied by an integer (m), the difference between the number (ns) of grooves (15) and the number (nr) of equivalent slots being different form zero, +2 and -2.
