Abstract
A method for manufacturing a stator for an electric machine, having the following steps: inserting a cast body with a nozzle from a first side of the stator into the stator, inserting a cast counterbody from a second opposing side of the stator into the stator, casting the stator with thermoplastic, thermosetting plastic, or resin by means of the nozzle, curing the thermoplastic, thermosetting plastic, or resin, wherein following the curing a cast-on piece of the thermoplastic, thermosetting plastic, or resin is sheared off using a rotational movement of the cast body or cast counterbody.
Claims12
A method for manufacturing a stator for an electric machine comprising
- Inserting a cast body with a nozzle from a first side of the stator to be casted into an inside of the stator to be casted
- Inserting a cast counterbody from a second opposing side of the stator to be casted into the inside of the stator to be casted to face the cast body,
- Casting the stator with thermoplastic, thermosetting plastic, or resin by means-of through the nozzle and a space between the cast body and the cast counterbody, and
- Curing the thermoplastic, thermosetting plastic, or resin,
- wherein following the curing, a cast-on piece of the thermoplastic, thermosetting plastic, or resin is sheared off using a rotational movement of the cast body or cast counterbody.
A device for manufacturing a stator for an electric machine, comprising:
- a cast body that is inserted into an inside of the stator to be casted from a first side of the stator to be casted,
- a nozzle arranged in the cast body,
- a cast counterbody that is inserted into the inside of the stator to be casted from a second, opposing side of the stator to be casted to face the cast body with the nozzle,
- a stator retaining device to hold the cast body and the cast counterbody so that the cast body and the case counterbody are disposed inside the stator to be casted, and
- a feed channel that is connected to the nozzle to feed thermoplastic, thermosetting plastic, or resin to a space between the cast body and the cast counterbody,
- wherein at least the cast body or the cast counterbody is rotatable.
