## Abstract

An electric motor, in particular for a motor vehicle, having a cylindrical motor housing and having a fastening flange, the motor housing having a housing shell which is open both on a first end side and on the opposite second end sides, the fastening flange being configured with a bearing seat, and the fastening flange being connected to the housing shell on the second end sides.

## Claims

### Claim 1

An electric motor for use in a motor vehicle, the electric motor comprising:
a cylindrical motor housing;
a fastening flange formed in a plate-like manner as a flange plate, wherein the fastening flange forms a bearing seat defining a triangular shaft leadthrough; and
a housing shell including a first end side and a second end side, opposite the first end side, wherein the first end side and the second end side are each open, the fastening flange is connected to the second end side of the housing shell by a weld seam bearing against the fastening flange over a full circumference of the housing shell, and wherein the fastening flange is connected to the housing shell on the second end side.

### Claim 2 (depends on 1)

The electric motor of claim 1, wherein the weld seam is a laser weld seam.

### Claim 3 (depends on 1)

The electric motor of claim 1, wherein the fastening flange is a bent part formed by stamping or by deep drawing.

### Claim 4 (depends on 1)

The electric motor of claim 1, wherein the fastening flange includes a number of fastening points disposed outside the housing shell.

### Claim 5 (depends on 1)

The electric motor of claim 1, wherein the first end side is wider than the second end side, wherein the first end side is opposite the fastening flange.

### Claim 6 (depends on 1)

The electric motor of claim 1, further comprising a bearing plate, wherein the bearing plate is inserted into the first end side of the housing shell.

### Claim 7 (depends on 1)

The electric motor of claim 1 further comprising a shaft extending through the shaft leadthrough.

### Claim 8

A motor housing for use in an electric motor, the motor housing comprising:
a hollow-cylindrical housing shell; and
a plate-shaped fastening flange connected to the housing shell by a weld seam extending around a full circumference of the hollow-cylindrical housing shell and including an integrated bearing seat defining a triangular-shaped shaft opening.

### Claim 9 (depends on 8)

The motor housing of claim 8, wherein the hollow-cylindrical housing shell includes a first end and a second end, opposite the first end, wherein the first end is wider than the second end.

### Claim 10 (depends on 9)

The motor housing of claim 9, further comprising a bearing plate, wherein the first end receives the bearing plate.

### Claim 11

An electric motor comprising:
a housing shell including a first end and a second end and extending in a first direction, wherein the first end and the second end are each open and the first end is wider than the second end;
a fastening flange having a substantially planar shape fixed to the second end of the housing shell by a weld seam extending around a circumference of the housing flange, wherein fastening flange extends in a second direction orthogonal to the first direction and forms a first bearing seat, wherein the first bearing seat defines a triangular-shaped shaft opening; and
a bearing plate disposed in the first end of the housing shell, wherein the bearing plate forms a second bearing seat, wherein the first bearing seat and the second bearing seat are configured to receive a shaft of the electric motor.

### Claim 12 (depends on 11)

The electric motor of claim 11, wherein the weld seam is a laser weld seam.

### Claim 13 (depends on 11)

The electric motor of claim 11, wherein the first bearing seat is formed by a protrusion extending from a plate portion of the fastening flange formed by stamping.

### Claim 14 (depends on 11)

The electric motor of claim 11, wherein the protrusion extends from the plate portion towards the first end.

### Claim 15 (depends on 11)

The electric motor of claim 11, wherein the fastening flange includes a number of fastening points disposed outside of a circumference of the housing shell.

### Claim 16 (depends on 11)

The electric motor of claim 11 further comprising a shaft extending through the triangular-shaped shaft opening.
