摘要： A core formed from powder, such as a stator core for use in a motor for a vehicle, wherein the core is formed from metallic powder and includes an outer part disposed at an inside of the motor, an inner part disposed at an inside of the motor, and a winding part which connects the outer part and the inner part and on which a wire is wound, and to a motor for a vehicle using the same. The winding part is formed to have rounded corners and a height lower than the height of the inner part, and a connection part is obliquely formed between the winding part and the inner part so that the winding part and the inner part are naturally connected.
