Abstract
The present disclosure provides a rotor of the wound rotor driving motor including: a first core body having an outer surface and an inner surface, wherein the first core body forms a space inside of the first core body; a second core body being inserted into inside of the first core body, wherein the second core body contacts with the inner surface of the first core body; and a coil assembly combined to the second core body in a radial direction.
Claims12
A rotor of a wound rotor driving motor, comprising:
- a first core body having an outer surface and an inner surface, wherein the first core body forms a space inside the first core body and has rotor shoes connected with each other at a predetermined space along a circumferential direction;
- a second core body forming a rotor tees, wherein the rotor tees contact with an inside of the rotor shoes in a radial direction and the second core body is inserted into an inside of the first core body;
- and
- a coil assembly combined to the rotor tees of the second core body,
- wherein the first core body is formed as an integral cylindrical shape and both ends of the first core body are open, and
- wherein the first core body comprises:
- walls integrally connecting both ends of the neighboring rotor shoes, wherein the walls are formed to protrude around a shaft of the second core body in the inner surface of the first core body.
