Abstract
A field-pole magnet manufacturing apparatus manufactures magnet pieces that constitute a field-pole magnet arranged in a rotary electric machine by fracturing the magnet. This manufacturing apparatus includes: a support unit on which the magnet is placed; a fracture unit that is arranged opposite to the support unit across the magnet and is configured to fracture the magnet by pressing the magnet while in contact with the magnet; and a powder removal unit that is configured to remove crush powder produced by fracture of the magnet.
