Abstract: The mounting of a coolant line system in a magnet device of an electric machine is to be simplified. Therefore, a magnet device is provided, with a ferromagnetic base member (4) comprising a first (3) and an opposite second side (5) and comprising penetration holes for coolant lines from the first side (3) to the second side (5), and a plurality of first coolant line segments (1) inserted through the holes. The first coolant line segments (1) are U-shaped and each of the free leg ends (2) thereof is inserted through two of the holes of the first side (3) such that the leg ends (2) protrude from the second side (5) of the base member (4). Two of the leg ends of the first coolant line segments (1) are connected by way of a second coolant line segment. Thus, only two types of coolant line segments are needed to construct the coolant line system, and also the coolant line segments can be connected at a single side (5) of the base member (4).

Abstract: A frame-like pressure flange arrangement on the backside of a frame for a yoke lamination stack comprises four spaced wall portions positioned at right angles to one another and connected with connecting pieces. The wall portions have the connecting pieces welded to them in such a manner that all the welds are recessed.

Abstract: The cooling arrangement for a machine provided with hollow fins has in the end regions of the stator housing ports for the internal air and below the stator housing, closed at one end by an end plate, in the region of the respective ports, a motor-driven internal fan which is laterally covered by an air deflection surface between it and the pierced inner bearing bracket. Between the inner shaft end and the motor attached to the end plate, a rotation sensor coupled with the shaft end is arranged and it is used for air conduction as well. In the fan shell a motor-driven external fan is arranged and its motor may be attached on the outer side of the end plate.
