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.

摘要： A one-piece field-pole magnet is manufactured by filling a gap formed between magnetic pieces placed on a plane with an adhesive or resin. During the process, a pushing member applies a pushing force onto each of the magnet pieces in a thickness direction thereof. The pushing member comprises pushing parts each of which pushes each of the magnet pieces, thereby equalizing the pushing forces applied to the respective magnet pieces.
