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.
Claims6
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.
