摘要:
Described herein is an axial-flux electric motor, comprising: a stator (7) made of ferromagnetic material, which supports a plurality of windings (9) set at angular distances apart from one another about an axis of rotation (11) of the motor; at least one rotor (13) facing the stator (7) and provided with a plurality of permanent magnets (15), set at angular distances apart from one another and arranged approximately on a plane perpendicular to the axis of rotation (11); and a cooling system (20) comprising an annular tubular metal body (22) coupled to the stator (7) and provided with at least one system for circulation of a fluid inside the body itself. The circulation system comprises a tube (30) with circular cross section with which a coil is made comprising three or four turns that extend inside the body (22) and are completely englobed in the metal material of which the body (22) itself is made.
摘要:
A device for cutting the umbilical cord (3) of a torpedo (4), and having: a substantially flat rotary member (10) defining a peripheral cutting portion (13) and having a hinge hole (14) by which to hinge it to an outer surface of the torpedo (4); and a flap (16) connected to the substantially flat rotary member (10) and defining an eye (17) through which to thread the umbilical cord (3). The flap (16) is movable between a raised work position, in which the flap (16) is crosswise to the substantially flat rotary member, and a withdrawn rest position, in which the flap (16) is substantially coplanar with the substantially flat rotary member (10).
摘要:
A shutter for a launch tube (3) for launching a countermeasure (4), wherein a support (10) has a circular opening (12) of a diameter (D) equal to the diameter of the launch tube (3). The shutter has a first and second flexible panel (15, 16) fitted to the support (10) and which, when undeformed and at rest, close the circular opening. The panels (15, 16) flex and deflect, as a front end portion (6) of the countermeasure (4) moves through the circular opening (12), to permit expulsion of the countermeasure (4) through the shutter (1), which is opened by the forward movement of the countermeasure.
