Abstract
A method for producing a stator assembly of an electric motor includes: providing a laminated core of the stator assembly; mounting at least one coil former on the laminated core; mounting a ground contact pin on the laminated core provided with the coil former; and overmolding the laminated core with plastic.
Claims7
A method for producing a stator assembly of an electric motor, the method comprising:
- providing a laminated core (1) of the stator assembly;
- mounting at least one coil former (2) on the laminated core (1);
- mounting a ground contact pin (4), formed as a lead frame pin, on the laminated core (1) in a receptacle (3) on the coil former (2) so that the ground contact pin (4) extends axially parallel to a longitudinal axis of the stator assembly;
- and
- overmolding the laminated core and a portion of the ground contact pin (4) with plastic after mounting the ground contact pin (4) on the laminated core (1) provided with the coil former (2),
- wherein an end of the ground contact pin (4), opposite the laminated core, is exposed from the overmolding.
