Abstract
The method includes using a yoke ring and a pole star ring with a plurality of stator teeth for the arrangement of windings, preferably winding packages. The pole star ring can be received in the yoke ring by inserting the pole star ring into the yoke ring. The stator teeth face the yoke ring. The pole star ring can be expanded, thereby causing the stator teeth to press against the yoke ring.
Claims20
A method for producing a stator for an electric motor, having the steps of:
- providing a yoke ring and a pole star ring with a plurality of stator teeth for arranging windings, preferably winding packages, wherein the pole star ring can be received in the yoke ring;
- inserting the pole star ring into the yoke ring, with the stator teeth facing the yoke ring;
- and
- spreading the pole star ring, such that the stator teeth are pressed against the yoke ring.
The method according to claim, wherein one or more inwardly projecting connecting pieces are provided in spaces between the individual stator teeth to form the pole star ring, and wherein the pole star ring is spread by pressing on the connecting pieces.
A stator for an electric motor, comprising:
- having a yoke ring and a pole star ring which can be accommodated in the yoke ring and which has a plurality of stator teeth, and an opening for arranging a rotor, as well as windings, which are arranged on the stator teeth,
- wherein the stator teeth of the pole star ring are connected to one another via stretchable connecting pieces, wherein the connecting pieces are plastically deformed in the mounted state compared to an original state of the stator, and wherein the stator teeth are pressed against the yoke ring compared to an original state.
The stator for an electric motor according to claim
- wherein the stretchable connecting pieces are designed as bent connecting pieces
