摘要： A fluid circulator including a pump body with an impeller; an electric motor having a rotor connected to the impeller for rotatably driving the impeller; an end portion associated with the motor body for housing at least one electronic board for controlling the circulator. The end portion is monolithically cup-shaped lid fitted onto the motor body in substantial continuity therewith enclosing a housing compartment for said electronic board; an electronic power device mounted onto the electronic board so as to face the end wall of the cup-shaped lid; at least one portion of said end wall being recessed towards the electronic board and being externally provided with at least one cooling fin extending in parallel to the axis of the motor to constitute a heat sink; and a layer of a heat-conductive paste material in contact with the electronic power devices and recessed surface.

摘要： The invention relates to an improved electric motor for a fluid circulator comprising a permanent magnet rotor (2), a stator (3), in which a supporting and containing hollow body (4) for the rotor (2) is housed, an impeller (5), a shaft (6) of the electric motor kinematically coupled to the rotor (2) and to the impeller (5) for activating the impeller (5) in rotation. Advantageously, the rotor (2) comprises an axial thrust bearing member (7; 10), made of anti-friction material and adapted for supporting axil loads produced during the fluid circulation in the circulator, said thrust bearing member being integrated inside the rotor itself, so that the thrust bearing member does not separate from the rotor during a motor disassembly.

摘要： The invention relates to a process for manufacturing a waterproof magneto-rotor (1) made of rare-earth elements, to be used in a synchronous electric motor having a rotor (2) with a permanent magnet and wherein the rotor (2) is solidly fixed to a shaft (3). The process comprises the following phases: a first phase of coating the rotor (2) with a first inner protective layer (12) obtained by a first injection moulding phase; a second phase of coating the first inner protective layer (12) of the rotor (2) with a second outer protective layer (14) obtained by a second injection moulding phase; at least one annular protective barrier (15) being shaped on at least one or both the opposed end surfaces of the rotor (2) during the first injection moulding phase, for preventing water or humidity from seeping between the first inner protective layer (12) and the second outer protective layer (14).

摘要： The invention relates to a synchronous permanent-magnet motor preferably used in fluid driving pumps and in particular circulators for heating and/or cooling plants, of the type comprising: a stator or stator stack housed in a circulator body; a permanent-magnet rotor; an electronic control board of the circulator, installed in a casing associated with the circulator body. Advantageously a direct internal electrical connection is provided between the stator stack 11 and the electronic board so as to form a functional earthing connection terminal. This connection is obtained by means of a terminal having one end fixed to the metal structure of the stator stack and the other end connected to said electronic board.
