Abstract
A driving motor includes a rotor body that is rotatably installed inside a stator with a predetermined void therebetween and has a rotor coil wound on multiple rotator teeth. The rotor body includes: i) multiple wedges inserted between the rotor teeth of the rotor body in an axial direction and supporting the rotor coil; and ii) end coil covers mounted on both axial ends of the rotor body, respectively and connected with the wedge members. Each wedge member includes a wedge body disposed between the rotor teeth in the axial direction and connected with the end coil covers. Each wedge body is made of a metallic material having a conductivity and has an insulating layer formed on an outer surface other than both cross sections connected to the end coil covers. The end coil covers are also made of a metallic material having a conductivity and are connected with the ends of each wedge body.
