Stator for rotating electric machine, rotating electric machine equipped with same, and manufacturing methods therefor
Provided is a stator for a rotating electric machine equipped with a connection terminal having high manufacturability and vibration resistance; also provided is a rotating electric machine equipped with this stator. The stator, which is for a rotating electric machine equipped with a stator coil, is equipped with a connection terminal. The connection terminal has a crimping part to which stator coil input/output coil conductors are connected, and a fastening part which is mechanically connected to an external mechanism, with a melt material arranged on the fastening part. The input/output coil conductors are configured so as to be connected to the connection terminal, with the melt material provided on the crimping part therebetween.
1. A stator of a rotating electric machine with a stator coil, comprising:
a connection terminal including a pressure connection portion and a fastening portion, the pressure connection portion being connected to an input/output coil conductor of the stator coil, the fastening portion being mechanically connected to an external system, wherein a melting material is disposed in the fastening portion.
2. The stator of the rotating electric machine according to claim 1 , wherein the input/output coil conductor is connected to the connection terminal through the medium of the melting material disposed in the pressure connection portion.
3. The stator of the rotating electric machine according to claim 2 , wherein the melting material is buried in a basic material of the connection terminal so that a surface of the basic material and a surface of the melting material become coplanar.
4. The stator of the rotating electric machine according to claim 3 , wherein the melting material is in a belt-like shape and stretches with respect to a side direction of the pressure connection portion and the fastening portion or a direction where the pressure connection portion and the fastening portion are brought into contact.
5. The stator of the rotating electric machine according to claim 1 , wherein the melting material is a brazing material.
6. A rotating electric machine comprising the stator according to claim 1 .
7. A manufacturing method for a stator of a rotating electric machine with a stator coil, wherein the stator includes a connection terminal including a pressure connection portion and a fastening portion, the pressure connection portion being connected to an input/output coil conductor of the stator coil, the fastening portion being mechanically connected to an external system,
wherein the connection terminal is cut off from a belt-like material buried with a belt-like melting material in a longitudinal direction so that the melting material is disposed in both the pressure connection portion and the fastening portion.
8. The manufacturing method for the stator of the rotating electric machine according to claim 7 , comprising:
burying two or more of the melting materials in the belt-like material; and
cutting off the connection terminals from the belt-like material in such a state that the pressure connection portion of one connection terminal and the fastening portion of another connection terminal are alternately arranged in the longitudinal direction of the belt-like material.
9. The manufacturing method for the stator of the rotating electric machine according to claim 7 , comprising:
alternately arranging the pressure connection portion of one connection terminal and the fastening portion of another connection terminal in the longitudinal direction of the belt-like material; and
cutting off the connection terminals from the belt-like material in such a state that the melting material is disposed so as to connect the pressure connection portion and the fastening portion of one connection terminal.
10. The manufacturing method for the rotating electric machine comprising the stator recited in claim 1 .
