An active roll stabilizer includes a divided torsion bar () having torsion bar parts () which are arranged one behind the other along a torsion bar axis. An actuator () for transmitting torsional torques to the torsion bar () is provided. An electric motor () and a transmission () connected to the electric motor () are arranged in an actuator housing (). The actuator housing () is connected to the one torsion bar part () for conjoint rotation and the transmission () is connected, on the output side, to the other torsion bar part () for conjoint rotation. A motor housing () of the electric motor () is connected, by means of only one of the two axial ends of said motor housing, to the actuator housing () for conjoint rotation.

Active roll stabilizer

The invention relates to an electric motor and a method for assembling the motor. Especially preferred is that the electric motor is for driving an antiroll stabilizer. The electric motor includes firstly a stator having at least one electromagnet and a rotor which can rotate about an axis relative to the stator. The electric motor also includes at least one bearing plate for receiving a bearing for rotatable mounting of the rotor. Disposed on the bearing plate is a retainer disc for retaining contacts. The contacts are for electrical connection of the at least one electromagnet of the stator and pass through the retainer disc. Fastening elements are used to fasten the retainer disc to the bearing plate. There is also a positioning arrangement for radial positioning of the retainer disc with respect to the bearing plate. According to the invention the positioning arrangement is designed for adjustable radial positioning of the retainer disc with respect to the bearing plate.
