Definitions
- An electric machine designed as a three-phase generator for motor vehicles, is known from German published patent application DE 44 25 000 A1. There is described that an air gap can be provided, which is arranged between a peripheral region of a housing part and the laminated core of the stator.
- stator is held in the housing via its outer teeth, the housing resting on an axial end face of the stator outer teeth and the stator outer teeth by one R. 307454
- Housing opening are included appropriately. This measure additionally improves the heat transfer from the stator iron via its stator outer teeth to the housing, since the stator outer teeth are at least partially in contact with the housing in the housing opening.
- the housing grooves run in an annular region of the housing part and also end in this.
- the design for example with regard to the length of these housing grooves, also influences the stability of the ring area with regard to the vibration properties and thus the sensitivity to breakage. Without the ends of the housing grooves in the ring area, the housing part would be weakened too much. It is envisaged that the housing grooves end with a slope. This has the advantage that the effective flow cross section is particularly large in the transition from the area outside the end windings of the stator iron or stator to the housing part. The flow can be guided better. In addition, the risk of contamination and thus clogging of these openings is reduced.
- Housing teeth is larger than an inner diameter of the stator outer grooves. This has the advantage that, directly in the plane in which the stand rests on the housing part, the blocking of the flow path through the housing teeth is particularly small. This means that the flow resistance in this flow path is reduced, and thus the coolant throughput with the known consequences is also improved.
- Cooling air can flow over the surface of the stator outer teeth for a longer period of time and the cooling effect for the stator or the stator iron is thus improved.
- Figure 6 is a partial view showing certain proportions in the transition from stator iron to the housing part.
- FIG. 1 shows a cross section through an electrical machine 10, here in the embodiment as a generator or three-phase generator for motor vehicles.
- This electrical machine 10 has i.a. a two-part housing 13, which consists of a first bearing plate 13.1 and a second bearing plate 13.2.
- the bearing plate 13.1 and the bearing plate 13.2 accommodate a so-called stator 16 which, on the one hand, consists of an essentially circular stator iron 17 and in which a stator winding 18 is inserted in the radially inward, axially extending slots. With its radially inwardly directed grooved surface, this annular stator 16 surrounds a rotor 20 which is designed as a claw pole rotor.
- the rotor 20 has a total of two axial end faces, to each of which a fan 30 is attached.
- This fan 30 essentially consists of a plate-shaped or disk-shaped section from which fan blades originate in a known manner. These fans 30 serve to enable an air exchange between the outside of the electrical machine 10 and the interior of the electrical machine 10 via openings 40 in the end shields 13.1 and 13.2. For this purpose, the openings 40 in
- FIG. 2 shows the transition from the housing 13 or housing part 13.1 to the stator 16 or stator iron 17.
- the housing 13 or housing part 13.1 has an annular region 50 which is connected via ribs 51 in the axial or radial direction to a plate-shaped section 52 of the housing part is.
- the housing part 13.1 thus has an essentially cup-shaped shape.
- openings 54 which serve to allow the cooling air which has passed through the winding overhang 45 to reach the outside.
- the ring area 50 serves to receive the stator 16.
- the stator 16 is held in the housing or housing part 13.1 in such a way that the stator 16 rests with one of its axial end faces 57 on an axial contact surface in the housing part 13.1 or ring region 50.
- One stator outer groove 64 also extends in the axial direction between two adjacent stator outer teeth 62. The stator 16 thus lies with an axial end face or the individual axial end faces 57 of its outer teeth 62 on an axial end face 58 of the ring region 50.
- stator outer teeth 62 are suitably received by a housing opening. To improve, i.e. to enlarge the stator outer teeth 62
- FIG. 4 shows a detail of an axial view of the joint between the housing part 13.1 and the stator 16.
- the stator outer teeth 62 and the stator outer grooves 64 arranged therebetween can be clearly seen.
- the ring region 50 is toothed or stuck at the location receiving the stator 16 grooved.
- the ring area 50 of the housing part 13.1 is thus serrated or grooved on the side facing the stator 16 over its inner circumference and thus externally resembles a so-called hollow gearwheel in this area.
- the housing grooves 70 face the stator outer grooves 64 or, in other words, that the housing teeth 71 face the stator outer teeth 62.
- FIG. 6 shows a simplified representation of the opposing housing teeth 71 or stator outer teeth 62, in the plane of the axial end face 58 or 57.
- An inner diameter DJ of the stator outer grooves 64 is defined as the diameter of the groove base of the stator outer grooves 64.
- the inside diameter DJZ of the housing teeth 71 is the smallest diameter described by the housing teeth 71. It is provided • in that on the one hand the housing slots 70 alternating with teeth 71 housing an inner diameter DJZ, the housing teeth 71 is greater than an inner diameter D of the stator slots JN 64th
- the housing teeth 71 should be wider in the circumferential direction than the stator outer teeth 62.
- stator outer teeth 62 are covered in a first approximation over a radial length of 40%> to 70% by housing teeth 71 or the axial end face 58. In a second approximation, the coverage is between 50% and 64%.
- stator iron 17 extends in relation to its entire axial length by at least one third to approximately half of it.
