Abstract

An electric motor comprises a stator and a rotor which is rotatably mounted in the stator, the stator having an exciter winding which can be energized via connecting contacts, in a stator housing. The connecting contacts are permanently connected to the stator housing, electrical connecting elements which are accessible from the outside in the radial and axial directions being connected to the connecting contacts.

Claims (13)

1. An electric motor, comprising:

a stator housing;

electrical connection elements;

connecting contacts connected to the stator housing, the connecting contacts configured to be connected to the electrical connection elements accessible from outside in directions to be connected, the connecting contacts integrated into the stator housing and forming part of the stator housing, the connecting contacts arranged as clamping elements cast into the stator housing;

a stator arranged in the stator housing and including an exciter winding energizable via the connecting contacts; and

a rotor rotatably mounted in the stator;

wherein the electrical connection elements include stud bolts insertable into the clamping elements.

2. The electric motor according to claim 1 , wherein the electric motor is configured for a steering system in a vehicle.

3. The electric motor according to claim 1 , wherein the connecting contacts are arranged on an axial end side of the stator housing and are radially accessible from the outside.

4. The electric motor according to claim 1 , wherein the stator is insertable into a motor housing, the connecting contacts accessible from the outside through radial openings in the motor housing.

5. The electric motor according to claim 1 , wherein the connection elements to the connecting contacts project on a side facing away from the connecting contacts into a control device connected to the stator housing.

6. The electric motor according to claim 1 , further comprising a cover cap arranged to cover the connecting contacts.

7. The electric motor according to claim 1 , wherein the electric motor is arranged as a three-phase asynchronous motor.
