Device for manufacturing permanent magnet

A permanent magnet manufacturing apparatus comprising:

• a compression molding mechanism;
• and
• a magnetic field generating mechanism,
• wherein the compression molding mechanism includes a pair of punches facing each other, and a die having a tubular shape into which the pair of punches are inserted,
• the magnetic field generating mechanism includes a pair of coils,
• the compression molding mechanism is disposed between the pair of coils,
• the compression molding mechanism does not penetrate through an inside of each of the pair of coils,
• the die includes a space between the pair of punches into which a raw material containing magnet powder is capable of being supplied,
• a magnetic field is generated by at least one of the pair of coils,
• the pair of punches is configured to compress raw material in the die while applying the magnetic field to the raw material in the die in order to form a compact from the raw material,
• the apparatus includes means for changing a direction of the magnetic field applied to raw material in the die by at least one of a movement of an entirety of the magnetic field generating mechanism, a rotation of the entirety of the magnetic field generating mechanism and a rotation of at least one of the coils,
• a pressing direction is defined as a direction in which the pair of punches face each other,
• a distance from a rotation axis of the entirety of the magnetic field generating mechanism to one coil is equal to a distance from the rotation axis to the other coil,
• the rotation axis is perpendicular to the pressing direction, and
• the entirety of the magnetic field generating mechanism is configured to rotate about the rotation axis.
