Title:
ELECTRIC MOTOR OF A DRIVE ARRANGEMENT IN A MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2010/057481
Kind Code:
A3
Abstract:
The invention relates to an electric motor of a drive arrangement in a motor vehicle, having a stator (1) and a rotor (3) disposed within the stator (1) and rotationally supported in a rotor bearing (2), wherein a motor housing (4) is provided and wherein the motor housing (4) receives the stator (1) and at least one part of the rotor bearing (2) and fundamentally ensures the concentric alignment between the stator (1) and rotor (3), wherein the motor housing (4) is engaged with the stator (1) at least some of the time by means of a separate centering arrangement (6) aligned to the motor axis (5), such that in case of particularly temperature-induced clearance between the motor housing (4) and the stator (1), the concentric alignment between the stator (1) and the rotor (3) is ensured.
