PROBLEM TO BE SOLVED: To provide a core for a motor that can effectively utilize an entire core as a magnetic path in the core for the motor made of magnetic powder.SOLUTION: At a core for a motor and the motor, the shape of the core for the motor which is wound with a coil to generate rotational driving force by magnetic action with a magnet comprises: a central core part having a central axis; a plurality of arm parts extending in the radial direction of a circle centering on the central axis from the central core part; and a blade part which is formed at the tip of each of the arm parts and extends from the tip to the circumferential direction of the circle and to the direction parallel to the central axis. At an end surface of the end extended to the direction parallel to the central axis of the blade part, a notch formed toward the arm parts is provided. |
