An electric synchronous motor having a stator (10) with electric windings (14) and a rotor (16) comprised by a spindle (20) and a magnetic core (22), wherein the core (22) is formed by a number of annular magnetic discs (21) piled on the spindle (20), separated electrically from each other by layers of insulating material (17), and axially clamped together by a prestress force high enough to increase the bending strength, i.e. the coefficient of elasticity, of the rotor (16). <IMAGE> |
