摘要: A field-pole magnet manufacturing apparatus fractures a magnet fixed on a die serving as a lower tool by causing a punch of an upper tool to press the magnet while in contact with the magnet. At least one projection is formed in the punch of the upper tool symmetrically with respect to the central position of the magnet in the width direction of the magnet.
