Abstract
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.

Synchronous permanent-magnet motor used in fluid driving pumps and, in particular, in circulators for heating and/or cooling plants, of the type comprising:
- a stator (11) or stator stack housed in a circulator body (15);
- a permanent-magnet rotor (2);
- an electronic control board (20) of the circulator (10), installed in a casing (16) associated with the circulator body (15), characterised in that a direct internal electrical connection is provided by means of a terminal (25) having one end (27) fixed to the stator stack (11) and the other end (28) connected to said electronic board (20) so as to form a functional earthing connection terminal;
- said terminal (25) being a connector fastened to the stator stack (11) by means of over-moulding.
