- the lines connected to one another in the lead frame by an external bridge part can be separated from one another at a suitable time during the manufacture of the motor arrangement by removing the bridge part.
- the plug part or its body is injection molded onto the circumference of the outer ring part, regions of the strand current line and the sensor line being embedded in the body of the plug part. This results in a particularly good fixation of the lines mentioned.
- annular seals for sealingly attaching the motor housing and / or for sealingly attaching a cover part are arranged on the body of the plug part, preferably by injection molding.
- the fixed bearing is fixed by a fixing part which is supported on the inner ring part.
- the side of the stator facing the plug part preferably engages in a receiving opening in the body of the plug part.
- the space between the outer and inner ring part, the areas of the current feed line and the sensor line arranged therein, and optionally the fixing part and the stator, are expediently cast into a unit by a casting compound and fixed to one another.
- a particularly stable unit results if the potting compound also encloses and fixes the outside and the side of the stator facing away from the plug part.
- the rotor with the shaft and a floating bearing arranged thereon on the side facing away from the plug part are inserted into the stator in such a way that the area of the shaft passing through the fixed bearing is fastened to the outside of the fixed bearing, preferably by prying.
- the floating bearing can also be attached to the shaft by prying.
- the motor housing is axially pushed onto the stator and the floating bearing in one manufacturing step and attached to the body of the plug part and fixed thereon. It is advantageous that the force acting on it is conducted over the stator block.
- a fastening area of a cover part attached from the side of the fixed bearing overlaps the end of the motor component facing the cover part. housing. In this way, the motor housing and the cover part are fastened to one another on the one hand and, on the other hand, to the unit of the motor arrangement at the same time.

- Figure 5 shows the insertion of the rotor assembly in the motor assembly according to the invention
- Figure 6 shows the mounting of the motor housing on the arrangement of Figure 5;
- Figure 7 shows the finished motor assembly according to the invention.
- a so-called lead frame of the present motor arrangement comprises a sensor line 2 and a line current feed line 3, which are connected to one another via a bridge part 4 (broken lines), which is later used at a suitable time point can be separated.
- the sensor line 2 and the line current supply line 3 are fixed in a molded part 5, which is preferably of annular design and has an outer ring part 5-1 and an inner ring part 5-2.
- the lines 2, 3 mentioned are preferably partially embedded in the outer ring part 5-1.
- pins 6 are preferably arranged, which receive a sensor board 7 and are preferably thermoformed for fastening the sensor board 7.
- the sensor board 7 can also be received or held via the lead frame 3. It is electrically conductively connected to the lead frame 3 by an axial channel 9 via a supply of heat.
- the lead frame 3 can be separated into the individual lines 2 and 3 by separating the bridge part 4.
