Definitions

  • the invention relates to an electric motor, in particular for a motor vehicle, having a pole-type motor housing with a front-side housing bottom and with an oppositely arranged end shield and a motor shaft mounted therein with a shaft-fixed rotor, which is surrounded by a housing-internal stator.
  • the power steering here supports a motor vehicle user when steering by the applied by the motor vehicle user steering force is supported for example with a hydraulic system or with an electric motor.
  • EPS electric motor assisted steering
  • an electric motor arranged on the mechanics of the steering wheel supports and superimposes the steering motions of the motor vehicle user with a generated auxiliary power.
  • So-called brushless electric motors (brushless DC motor, BLDC motor) are increasingly used for such electric motor drives (steering drives), in which the wear-prone brush elements of a rigid (mechanical) commutator are replaced by an electronic commutation of the motor current.
  • Such a brushless electric motor as an electric (three-phase) machine basically has a fixed (stationary) stator with a stator lamination Package with a number of, for example, star-shaped stator teeth.
  • the stator teeth carry a rotating electrical field winding in the form of individual (stator) coils or coil windings (phase windings), which in turn are wound from an insulated wire (coil wire).
  • the phase windings are associated with the coil or phase ends of individual (motor) strands or (motor) phases and interconnected in a predetermined manner.
  • the stator has three phases and thus at least three phase conductors or phase windings, which are supplied in each case out of phase with electrical current to produce a magnetic rotating field in which a usually provided with permanent magnets rotor or rotor rotates.
  • the phase ends of the phase windings are guided to drive the electric motor via phase connections to an engine electronics.
  • the coil windings of the rotating field winding are in this case interconnected by means of the coil ends in a certain way.
  • the type of interconnection of the coil ends is determined by the winding scheme or the winding structure of the rotating field winding, wherein as a winding scheme, a star connection, a triangular circuit or a combination thereof is common.
  • Stators for steering drives are usually stored or suspended in the region of their outer circumference in a motor housing of the electric motor. It is desirable that the stator and thus the electric motor designed as possible space-saving and low-weight (constructed). This can be achieved, for example, in that a cylindrical stator yoke encompassing the stator teeth has the smallest possible radial thickness. However, this leads in the electromotive operation to the fact that the Statorjoch bulges radially inward in the region of the connection points of the stator teeth due to the electromotive forces occurring. This can undesirably lead to a noise and / or vibration of the stator in the engine or drive housing (structure-borne sound), which adversely affect the acoustic properties of the electric motor or the steering drive.
  • the decoupling ring In the assembled state, the decoupling ring lies against the inner wall of the motor housing only with its axial outer ring section facing away from the stator, while the outer diameter of the inner ring section of the decoupling ring facing the stator is less than or equal to the outer diameter of the stator.
  • the decoupling axial wing flaps are formed, which engage in corresponding joining contours of the stator.
  • the decoupling ring is fixated on the housing side in a torsion-fixed manner on the housing side.
  • decoupling ring which has at its (housing side) outer ring portion a number of radially raised and azimuthally spaced system cam for radial mounting and mounting of the stator relative to the motor housing.
  • decoupling rings are necessary for different topologies of the rotating field winding - for example in the case of an 8-pole or 10-pole version of the electric motor - in order to reliably suppress the noise development.
  • decoupling rings require an additional axial space above and / or below the stator, whereby the size of the electric motor or the steering drive is adversely increased.
  • there is a tolerance chain with regard to the radial distance between the outer circumference of the stator and / or the decoupling ring and the inner circumference of the motor housing which has a significant influence on the coaxiality with the rotor, and thus influences the acoustics, disturbance torques and the producible torque of the drive ,

  • the greatest possible reduction in noise or structure-borne sound development should be realized.
  • the electric motor according to the invention is suitable and furnished in particular for a motor vehicle, for example for an electromotive steering drive.

  • the bearing plate is formed, for example, as a housing closing the motor housing, which is arranged on the housing bottom opposite end face of the motor housing.
  • the housing bottom is designed as a complementary bearing plate.
  • a motor shaft is mounted with a shaft-fixed rotor, wherein the rotor is surrounded by a housing-internal and housing-fixed stator.

Furthermore, this (radial) tolerance requirements of the stator and / or the motor housing are reduced. This translates into the consequence advantageous to a reduction in manufacturing costs.
  • the stator comprises a stator lamination stack with a number of stator teeth arranged radially inwardly and in a radial direction.
  • the stator teeth are provided with a multi-phase rotating field winding, each phase comprising at least one coil or coil winding (phase winding) having a first and a second coil end, by means of which the respective coil is electrically connected.
  • the coils are arranged, for example, as individual coils on a respective stator tooth and in the assembled state are connected to the (motor) phases, for example by means of a contact device that can be placed on the stator lamination stack at the front side.
