Definitions
- the invention relates to an electrical machine with a housing.
- the invention also relates to a drive unit for a motor vehicle with such an electrical machine.
- a yoke of the electrical machine is electrically insulated from the housing and coupled to the housing ground via an inductance. This reduces interference currents in the housing.
- the yoke of the electrical Ma machine is fastened via radially aligned screw connections in the housing.
- FR 2 115 648 A5 describes a structure for an electrically driven pump.
- the electric motor of the pump has a laminated stator core which is fastened to a housing by means of screws. Electrically insulating spacers are arranged between the housing and the laminated stator core.
- an electrical machine with a housing is proposed.
- the electrical machine is arranged inside the housing and has a non-rotatable stator and a rotatably mounted rotor.
- the stator is electrically isolated from the housing.
- the stator has a laminated stator core on which at least one stator winding is arranged. Several winding phases can be arranged on the laminated stator core.
- the laminated stator core together with the at least one winding is fastened to the housing by means of a plurality of screws aligned in the axial direction. Under .axial direction 1 is the Understood the direction of the rotor axis of rotation.
- Electrically insulating spacers are arranged between the stator lamination package and the housing.
- at least two centering pins are provided. The centering pins are used to center the Sta tor in the housing.
- an electrical machine which not only has an electrically insulating, axially aligned screw connection of the stator to the housing, but also an electrically insulating centering of the stator with respect to the housing.
- each of the centering pins is arranged at one end in a housing bore and at the other end in a centering receptacle of the laminated stator core.
- the centering pin is metallic, with the centering receptacle in the stator laminated core forming electrical insulation between the centering pin and the stator laminated core.
- a metallic centering pin which is made, for example, of steel, is less brittle than, for example, a centering pin made of ceramic. Such a construction is therefore particularly advantageous for difficult assembly conditions in which a high mechanical load acts on the centering pins.
- the electrically insulating centering receptacle is preferably formed by electrically insulating sleeves, for example ceramic sleeves, which are each inserted into a recess in the laminated stator core.
- electrically insulating sleeves for example ceramic sleeves, which are each inserted into a recess in the laminated stator core.
- Such sleeves have a high level of strength and can easily be carried out with the accuracy required for centering.
- the centering pins can consist of an electrically insulating material, for example ceramic.
- An electrically insulating design of the centering mount in the laminated stator core can be omitted.
- At least one of the spacers preferably has a through hole, at least one of the centering pins being passed through the through hole.
- At least one of the spacers is preferably held in position by the centering pin.
- the fit between the through hole and the centering pin is preferably so precise that a displacement of the spacer on the centering pin is only possible against a resistance. This also ensures that the spacer is held securely during assembly.
- the spacer is clipped into the housing.
- the spacer can have shoulders on two opposite sides, for example, which interact with a corresponding receptacle on the housing.
- the spacer is held securely on the housing so that the housing can be pivoted during assembly.
- the through hole should be chosen large enough so as not to cause any tension in the centering pin.
- At least one of the centering pins is made in one piece with one of the spacers. Centering pin and spacer thus only form a single component.
- Such a spacer together with a centering pin is made from an electrically insulating material, for example from ceramic.
- At least one of the spacers has a mounting pin which interacts with a receiving bore in the housing.
- a construction can simplify the assembly of the spacers on the housing.
- At least one of the spacers is preferably glued to the laminated stator core or to the housing. This gives the spacer a particularly good protection against loss, especially if the stator lamination package or the housing is preassembled at different locations or if these components are swiveled during the installation.
- the screws preferably do not touch the spacers. In other words, an air gap is preferably seen between the screws and the spacers. This prevents the spacers from being damaged when the laminated stator core is screwed onto the housing.
- Each of the screws is preferably passed through a through hole in the spacer.

- 1d shows a further configuration of a motor vehicle drive train which, in contrast to the drive trains according to FIGS. 1 a to 1 c, is a purely electric drive train without an internal combustion engine.
- An electric axle drive EA has an electric machine EM, the drive power of which is distributed to drive wheels DW of the motor vehicle via the Differentialge gear AG.
- Such a drive train could also have a transmission between the axle drive EA and the differential gear AG, for example a 2-speed transmission.
- Such an electric axle drive EA could also be combined with a second axle driven by an internal combustion engine.
- the hybrid modules HY, HY2, the hybrid transmission G and the axle drive EA form drive units for the motor vehicle.

- the laminated stator core SB has through openings SB1 through which the screws SS are passed in the axial direction.

- the stator S is electrically isolated from the housing GG in order to reduce the transmission of interference currents originating from the stator S via the housing GG and via the bearing WL to the rotor shaft RW.
- electrically insulating spacers SD are arranged between the stator lamination stack SB and the housing GG. These spacers SD consist, for example, of ceramic or a high-pressure-resistant plastic. Electrically insulating spacers SD2 are also arranged between a screw head of the screws SS and the stator lamination packet SD.
- Fig. 2b shows a further schematic sectional view of the drive unit HY, HY2, G, EA. This shows the centering of the stator S in the housing GG.
- Two centering pins SC are provided for centering, with only one of these two centering pins SC being shown in the illustration according to FIG. 2b.
- One end of the centering pin SC is arranged in a hole GG2 in the housing GG, the other end of the centering pin SC is arranged in a centering receptacle SBZ in the stator lamination stack SB.
- the centering receptacle SBZ is formed by a recess SB2.
- the centering pins SC are made of an electrically insulating material, such as ceramic.
- the centering pins SC are fitted into the bores GG2 and into the recesses SB2.
- the holes GG2 and the centering mount SBZ have a low position tolerance with respect to the axis RA in order to ensure an air gap between stator S and rotor R that is as uniform as possible.
- the centering pin SC leads through the spacer SD.
- FIGS. 3a to 6b Various embodiments are possible for this purpose, which are described by way of example in FIGS. 3a to 6b.
- the centering pins SC are made of a metallic material, for example steel.
- the centering receptacle SBZ has electrically insulating sleeves SBH, which are each inserted into a recess SB3 of the stator lamination package SB.

- the spacer SD is plate-shaped and has a through hole SDA1 and a through hole SDA2. When installed, one of the screws SS leads through the through hole SDA1.
- the through hole SDA1 is larger than the diameter of the screws SS.
- Projections SDX are formed on two opposite edges of the spacer SD. These are used to hold the spacer SD in the housing GG so that the spacer SD remains securely in position during assembly before the stator laminated core SB is attached to the Housing GG is attached.
- the spacer SD can be clipped into corresponding receptacles in the housing GG via the projections SDX.
- FIG. 3b shows a sectional view through the spacer SD through a sectional plane A-A given in FIG. 3a, the centering pin SC also being shown.
