Embodiment Construction

[0073] special reference figure 1 , reference numeral 1 denotes an electric machine according to the invention.

[0074] In one embodiment, the machine 1 is, for example, an electric motor of the hermetic type, that is to say without any openings for access to the interior, to which reference will be made hereinafter without loss of generality, it being understood that Unsealed or open motors or motors or other electrical or electronic devices in which the electronic control circuitry is located in its own housing attached to the motor or even outside the motor are also included.

[0075] The electric machine 1 is described in detail below only to the extent necessary for understanding the present invention.

[0076] The machine 1 comprises a housing 2 and a cover 3 covering the housing 2 to form an enclosure or external container with the housing 2 .

[0077] The electric machine 1 includes a stator 4 fixed to a casing 2 and a rotor 5 inserted into and rotatably connected ...

Abstract

An electric machine comprises a casing, a cap covering the casing to define an enclosure, a heat sink, an electronic module mounted inside the enclosure and comprising a printed circuit board having a first conductive layer defining, at least partly, a first face, or top face, of the printed circuit board, a second conductive layer defining, at least partly, a second face, or bottom face, of the printed circuit board, a plurality of vias which pass through the printed circuit board between the top face, at the first conductive layer, and the bottom face; the electronic module comprises at least one electronic component soldered to the printed circuit board on the first conductive layer by its own base and disposed, at least partly, on top of a first part of the vias, a conductive mass, soldered to the printed circuit board in proximity to the electronic component and disposed, at least partly, on top of a second part of the vias; the conductive mass forms part of the circuit of electrical connections through which the electric power supply of the electric machine flows and is in electric and heat exchange relationship with the electronic component, while the second face is in heat exchange relationship with the heat sink.

Description

technical field [0001] The present invention relates to a rotating electric machine, in particular to an electronic module for driving the machine and preferably built into the machine. [0002] In general, a rotating electric machine (eg, a brushless electric motor) to which reference is made below but which does not limit the scope of the invention includes a housing internally having a stator rigidly connected to the housing and rotatably connected to a The rotor of the housing, which has, for example, permanent magnets. [0003] The housing is covered by a cover to form a receptacle from which connection pins protrude to allow power and control of the electronic drive circuit. [0004] The electronic module or electronic drive circuit connected to the stator and mounted inside the motor comprises a printed circuit board and a number of active and passive electronic components mounted on the so-called component side of the printed circuit board.
