Definitions
- the present invention relates to a method for producing a stator assembly of an electric motor.
- the stator lamination of electric motors should be electrically connected to ground in order to be able to comply with the prescribed EMC limit values (electromagnetic compatibility).
- EMC limit values electromagnettic compatibility
- stator assemblies usually have a completely molded stator lamination, the electrical contacting is made more difficult.
- This problem has been solved, for example, as follows: via shielding through a metallic housing, via a ground connection via the press connection of the stator lamination and actuator housing, or via subsequent contacting via the stator bore, electrically conductive grease and a silver-plated contact spring.
- no ground connection was seen at all, which resulted in poor electromagnetic compatibility.
- the present invention has for its object to provide a method for manufacturing a stator assembly, which enables the implementation of a ground connection in a particularly effective manner.
- the ground contact pin is preferably mounted on the coil former in contact with the laminated core.
- the ground contact pin is preferably mounted in a receptacle on the coil former. The ground connection is therefore made with the help of the assembled coil former.
- the ground contact pin is mounted as a press fit pin.
- a press-fit connection is produced with the receptacle provided on the coil former, the required contact with the laminated core of the stator assembly being realized by this press-fit connection.
- the method according to the invention takes place in such a way that a coil former provided with a receptacle for the pressfit pin is mounted on the laminated core, after which the pressfit pin is inserted into the receptacle for producing a pressfit connection and is pressed with it .
- contact of the press-fit pin with the laminated core is achieved in order to prepare the appropriate ground connection.
- the laminated core can then be overmolded accordingly.
- a lead frame pin is preferably used as the ground contact pin or press-fit pin.
- the ground contact pin is preferably connected to the printed circuit board of the stator assembly.
- the ground contact pin can also be arranged in such a way that the at least one assembled coil former is additionally fixed to the ground contact pin.
- a plurality of mas contact pins can also be mounted, each having a mass contact pin being assigned to a coil former.
- a stator assembly three bobbins are mounted on a laminated core, and three ground contact pins are attached to the bobbins in contact with the laminated core, one ground contact pin being assigned to one bobbin.
- the present invention further relates to a stator assembly which has been produced by a method of the type described above.
- a laminated core 1 which has three recesses for the respective accommodation of a coil former 2.
- the upper two figures of the figure show how a coil former 2 is mounted on the laminated core 1 by being pushed onto a tongue in a recess.
- the third illustration from above shows how the coil body has reached its radial end position in the corresponding recess. It has a pocket-shaped receptacle 3 at its radial end, into which a press-fit pin 4 is inserted from above and connected to the receptacle 3 of the coil body 2 with a press-fit connection. The lower end of the press-fit pin 4 comes into contact with the laminated core 1 in order to achieve a ground connection there.
- the fourth illustration from above shows the pressfit pin 4 in its end position.
- stator assembly produced in this way which is provided with corresponding ground contact pins 4, is then encapsulated with plastic in a suitable manner, so that the object shown in the figure below results.
- three coil bodies 2 are each provided with a press-fit pin as ground contact pin 4, which is connected to the respective coil body via a press-fit connection and ensures a ground connection to the laminated core 1.
- ground contact pins 4 provided in this way are then brought into contact with a printed circuit board (not shown here). This also fixes the circuit board in addition to the desired ground connection.
