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.

An actuator apparatus is described as having a stator device, a cover device, a contact device and an attenuation device. The stator device and the cover device are joined in such a manner so that a hollow space is formed between the stator device and the cover device. The cover device has an opening, through which the contact device is guided into the hollow space, so that the contact device runs at least partially in the hollow space and at least partially in the cover device. The attenuation device is positioned in the opening in such a manner so that a high-frequency electromagnetic radiation that travels through the opening is more highly attenuated by the attenuation device than the radiation would be attenuated without the presence of the attenuation device.
