Definitions
- the present invention relates to rotating electric machines with liquid cooling, and more particularly liquid-cooled electric motors, especially water.
- some parts of a rotating machine may or may not require cooling.
- it may be necessary to cool the pivot, and thus provide the bearings of a cooling system.
- it may be superfluous to use cooled bearings.
- the invention aims to further improve rotating electrical machines and reduce the diversity of parts constituting them to facilitate their maintenance and industrialization.
- this carcass being cooled by a liquid cooling circuit, and having at least two connections communicating with this cooling circuit, the two connections allowing the supply and the return of coolant; flange when the latter is intended to be cooled by a circulation of the coolant.
- the invention thus also relates to a range of at least two rotating machines according to the invention, the carcasses of the two machines being identical, at least one of the machines comprising a flange cooled by liquid and at least one other machine having a flange not cooled by liquid.
- the subject of the invention is also a method for manufacturing a range of rotating electrical machines according to the invention, in which a plurality of identical carcasses is manufactured, and bearings are assembled on each carcass with liquid or non-liquid cooled bearings. needs ; in the case of a liquid cooling of the bearing it is connected to the connections of the carcass, and in the case of non-cooling of the bearing by liquid, the connections of the carcass are not used or connected to each other.
- the two connections are preferably connected together to allow circulation of the coolant between them when the flange does not have to be cooled by circulation of the coolant. This makes it possible not to cut the liquid circulation circuit of the carcass.
- the two connections are located near the corresponding flange.
- the electric machine according to the invention may comprise two pairs of connectors, each for cooling a corresponding flange of the machine.
- each pair of connectors may be located near the corresponding flange.
- connection between the connections of the carcass and the corresponding flange preferably takes place using external conduits, preferably rigid. This can advantageously facilitate the removability of the latter, and the change of the bearings, while promoting the cooling of the liquid at the level of the pipes.
- connection between the connections in the absence of liquid cooling of the flange is preferably performed by a single piece, attached to the carcass.
- the use of a single piece limits the number of parts while limiting the risk of leakage.
- the rotary electrical machine according to the invention is preferably a motor.
- the engines using liquid circulation cooling are for example the engines used in naval applications.
- the machine according to the invention can be such a motor, and the coolant can then be seawater.
- FIG. 1 represents an example of a rotary electric machine according to the invention, comprising bearings cooled by a circulation of coolant, and
- FIG. 2 represents an example of a rotating electrical machine comprising the carcass of the machine of FIG. 1 with bearings uncooled by a circulation of cooling liquid.
- FIG. 1 shows a rotary electric machine 1, in this case a motor, comprising a carcass 10 constituting a relatively closed and sealed enclosure, preferably having a protection index with water IP55 or higher.
- the carcass 10 is of elongated shape along an axis X, being closed at both ends by flanges 20 which define a front side and a rear side.
- Each flange 20 carries a bearing 21, associated with a shaft 23 by means of bearings not shown.
- the engine is cooled by a circulation of liquid F, for example water, which comes from an external source and enters the carcass 10 at an inlet 31, circulates in channels inside the carcass 10, passes at the level of connections 40, and leaves outward at an outlet 33.
- liquid F for example water
- the bearings are liquid-cooled, as illustrated in FIG. 1, the bearings comprise connectors 41 which are connected to the connections 40 of the carcass 10 via external conduits 50. The circulation of liquid then passes successively:
- connections 40 of the carcass are connected to each other by means of a single piece 60 attached to the carcass 10, preferably in a leaktight manner. . In this way, the flow of liquid passes through the same parts of the carcass 10 as in the case illustrated in FIG.
- the coolant is for example seawater.
- the circulation of liquid makes it possible to cool the stator.
- the invention is not limited to the example which has just been described and can in particular be applied to electric motors in non-marine applications.
- the coolant can circulate in a closed loop between the engine and a cooling system of this liquid or alternatively in an open circuit, the water injected into the engine being released into the environment, which may be the case for example of cooling with seawater.
