Abstract

A rotor of a wound rotor synchronous motor includes: a rotor body coupled to a rotation shaft and around which a rotor coil is wound; and a slip ring module mounted on one portion of the rotation shaft, the slip ring module comprising a brush contact portion configured to contact a brush, a terminal mounting portion connected to the brush contact portion, and a fusing terminal mounted at an exterior circumferential surface of the terminal mounting portion and connected to the rotor coil.

First claim

What is claimed is:

1. A rotor of a wound rotor synchronous motor, comprising:
a rotor body coupled to a rotation shaft and around which a rotor coil is wound; and
a slip ring module mounted on one portion of the rotation shaft, the slip ring module comprising a brush contact portion configured to contact a brush,
a terminal mounting portion connected to the brush contact portion, and
a fusing terminal mounted at an exterior circumferential surface of the terminal mounting portion and connected to the rotor coil,
wherein the fusing terminal is connected to the rotor coil within a range of a width of the terminal mounting portion and receives fusing pressure in a direction perpendicular to a surface including an axial direction of the rotation shaft.

2. The rotor of claim 1 , wherein the fusing terminal comprises:
a fixing portion having a width corresponding to the width of the terminal mounting portion, and fixed at the terminal mounting portion; and
a connection portion integrally connected to the fixing portion, and connected to the rotor coil.

3. The rotor of claim 2 , wherein the fixing portion is fixed at the exterior circumferential surface of the terminal mounting portion in a circumferential direction of the terminal mounting portion, and
the connection portion is twisted from the fixing portion and is bent in the circumferential direction of the terminal mounting portion.

4. The rotor of claim 2 , wherein a width direction of the fixing portion intersects a width direction of the connection portion.

5. The rotor of claim 3 , wherein the connection portion is oriented at a 90 degree angle with respect to the fixing portion.

6. The rotor of claim 3 , wherein a width direction of the connection portion is parallel to a width direction of the terminal mounting portion.

7. The rotor of claim 3 , wherein the connection portion is disposed within the range of the width of the terminal mounting portion, and a width of the connection portion is equal to the width of the terminal mounting portion.

8. The rotor of claim 3 , wherein the connection portion receives the fusing pressure in a direction perpendicular to a width direction of the connection portion.

9. The rotor of claim 3 , wherein the connection portion receives the fusing pressure in a width direction of the fixing portion.

10. The rotor of claim 3 , wherein the fusing terminal further comprises a twist portion twisted from the fixing portion.

11. The rotor of claim 10 , wherein the fixing portion is integrally connected to the connection portion through the twist portion.

12. A rotor of a wound rotor synchronous motor, comprising:
a rotor body coupled to a rotation shaft and around which a rotor coil is wound; and
a slip ring module mounted on one portion of the rotation shaft, the slip ring module comprising a brush contact portion configured to contact a brush,
a terminal mounting portion connected to the brush contact portion, and
a fusing terminal mounted at an exterior circumferential surface of the terminal mounting portion and connected to the rotor coil, and
wherein the fusing terminal comprises a fixing portion fixed at the terminal mounting portion, and
a connection portion twisted from the fixing portion outwardly in a radial direction of the rotation shaft, disposed within a range of a width of the terminal mounting portion, and receiving fusing pressure in a direction perpendicular to a surface including an axial direction of the rotation shaft to be connected to the rotor coil.

13. The rotor of claim 12 , wherein the fusing terminal further comprises a twist portion integrally connecting the fixing portion to the connection portion.

14. The rotor of claim 12 , wherein the connection portion is bent in a circumferential direction of the terminal mounting portion.

15. The rotor of claim 12 , wherein the fixing portion has a width corresponding to the width of the terminal mounting portion and a width direction of the fixing portion corresponds to a circumferential direction of the mounting portion.

16. The rotor of claim 15 , wherein the width direction of the fixing portion intersects a width direction of the connection portion and the width direction of the connection portion is parallel to a width direction of the terminal mounting portion.

17. The rotor of claim 16 , wherein the connection portion receives the fusing pressure in a direction perpendicular to the width direction of the connection portion.
