Abstract

A drive device, preferably a window raising mechanism drive, in a motor vehicle, includes a drive housing, in particular a gear mechanism housing, and a brushless electric motor, disposed in the drive housing and having a stator with a stator base member, which is disposed on a housing-secured, tubular stator carrier and is intended for a stator winding, and a rotor with a rotor shaft, which is guided into the drive housing or gear-mechanism housing by the stator carrier. The stator carrier is integrated in one piece in the drive housing or gear-mechanism housing.

Claims (14)

1 . A drive apparatus, electromotive adjustment drive or window raising mechanism drive, of a motor vehicle, the drive apparatus comprising:

a gear mechanism housing and a motor housing, said gear mechanism housing and said motor housing being detachably connected to one another to form a drive housing; and

a brushless electric motor disposed in said motor housing, said brushless electric motor having:

a tubular stator carrier secured to said gear mechanism housing,

a stator with a stator winding and a stator base member disposed on said tubular stator carrier for said stator winding, and

a rotor having a rotor shaft guided by said stator carrier into said gear mechanism housing,

said stator carrier being integrated in one piece in said gear mechanism housing;

said gear mechanism housing having a housing portion receiving said rotor shaft, said housing portion having an inner side; and

said stator carrier being a tubular or bush-shaped plastic material component injection-molded onto said housing portion, and said stator carrier being injection-molded at said inner side of said housing portion.

2 . The drive apparatus according to claim 1 , wherein said housing portion has an inner diameter, and said stator carrier has an inner diameter being smaller than said inner diameter of said housing portion axially outside the stator carrier.

3 . The drive apparatus according to claim 1 , wherein said gear mechanism housing has a housing space receiving said stator and said rotor, and said stator carrier has a carrier portion carrying said stator base member and protruding into said housing space.

4 . The drive apparatus according to claim 1 , which further comprises a bearing for said rotor shaft, said bearing being received in said stator carrier.

5 . The drive apparatus according to claim 1 , wherein said stator base member is a lamination bundle.

6 . The drive apparatus according to claim 1 , which further comprises a flange connection detachably connecting said gear mechanism housing and said motor housing to one another to form a drive housing.
