Problems solved by technology

[0012] But its disadvantage is that it is necessary to machine the large-sized workpieces (with corresponding notches) constituting the shell and make them tightly connected to each other in order to construct the distribution channel, which requires more time and higher cost, and may limit the durability of the associated components

Embodiment Construction

[0043] figure 1 The shown first distribution pipe 1 is cast into a part 2 made of metal. The first distribution pipe is substantially annular, but not completely annular. Part 2 consists of figure 2 Make an icon. The first distribution pipe is circular, but not complete, and forms a plane. The end of the first distribution pipe must not be closed, since the end needs to be closed by the pouring process. Part 2 can also be constructed as an end cap, in which case part 2 can house a ball bearing for mounting the motor shaft.

[0044] image 3 Shown is one embodiment of a cooling circuit. The cooling circuit essentially consists of a cooling pipe 3 and a part 2 into which the first distribution pipe 1 is cast. Bore holes through the first distribution pipe 1 are arranged at several points 4 of the part 2, through which the cooling pipe 3 can be inserted into the part 2 in a form-fitting manner and the cooling pipe 3 can be connected to the first distribution pipe 1. clos...

Abstract

The invention relates to an electric machine (6) comprising a rotor and a stator, the rotor having a shaft (7) and the longitudinal extension of the electric machine (6) being defined by the shaft axis. The electric machine (6) can be cooled by means of a cooling circuit, the latter comprising at least one cooling pipe (3), which extends essentially in the longitudinal direction of the electric machine (6). The cooling circuit comprises a first circular distribution pipe (1) that forms almost a complete circle, which stretches over one plane, the axis of the longitudinal extension of the electric machine (6) being essentially perpendicular to said plane.; According to the invention: at least one cooling pipe (3) can be connected in a water-tight manner to the first distribution pipe (1); the cooling circuit can be traversed by a coolant and has a first connection (10), which allows coolant to be supplied to the cooling circuit; and the cooling circuit has a second connection (9), which allows coolant to be evacuated from the cooling circuit. The first distribution pipe (1) is cast in one piece (2) from metal and said piece (2) has openings (4) for the cooling pipes (3) at the connection points of the first distribution pipe (1) to the cooling pipes (3). Once installed, the piece (2) is connected to the housing of the electric machine (6) so that it can conduct heat and / or forms an integral part of the housing.
