PURPOSE: A powder core and a vehicle motor using the same are provided to save coil weight by 50% using a copper aluminum coil, as reducing amount of used coil and achieving compactness of the motor by applying an isotropic powder core with high shape degree of freedom to a motor core. CONSTITUTION: A powder core(100) includes an outer part(140), an inner part(120) and a winding part(160). The outer part is formed with metal powder, and is located in the outside of a motor. The inner part is located in the inside of the motor. The winding part connects the outer part and the inner part, and is wound with a coil In the winding part, an edge is formed through rounding processing, and height(b) is smaller than height(a) of the inner part. A part(164) where the winding part contacts with the inner part is formed to be naturally connected to form an oblique shape. |
