Embodiment Construction

[0066] The drawings are given as examples and do not limit the invention. They constitute schematic representations intended to facilitate the understanding of the invention and are not necessarily drawings to the scale of actual application. In particular, the dimensions of the various components may not represent reality.

[0067] In the following, although all figures show motors or generators with axial flux, the invention is also applicable to motors or generators with radial flux.

[0068] The adjective “longitudinal” must be understood with reference to the central axis 5 , which runs transversely to the rotor 2 .

Abstract

The invention relates to a permanent-magnet synchronous motor or generator comprising at least one rotor (2) and at least one stator (3, 8). The motor comprises two rotors (2), four stators (3, 8) anda cooling system (7, 7a) comprising three cooling circuits (7, 7a), i.e. two outer circuits (7) which are each accommodated in a longitudinal outer wall of a casing (8), adjacent to an outermost stator (3, 8), for cooling said outermost stator (3, 8), and an intermediate circuit (7a) located between the two innermost stators (3, 8) in the motor for simultaneously cooling said two stators (3, 8),the central shaft (5) being common to the two rotors (2) which are connected to the central shaft (5) by mechanical means.

Description

technical field [0001] The invention relates to an electromagnetic motor or generator with two rotors and four stators and an integrated cooling system for optimizing the cooling of the motor or generator. Background technique [0002] The invention has an advantageous but non-limiting application in electromagnetic motors that transmit high power through high speed rotation of the rotor, obtained due to the interaction of the specific properties of the rotor according to the invention with those of the stator. Electric motors or generators of this type can be used, for example, as electromagnetic motors in all-electric or hybrid vehicles. [0003] In high-speed applications, not only is it necessary to achieve an optimal output by reducing the weight and size of the axial motor to achieve a compact system, but also the rotating part (i.e., the rotor) is required to have very high mechanical strength to increase the reliability of the system and stator reliability. [0004...
