Abstract
A manufacturing device for a field pole magnet body includes a reference jig having reference surfaces in the lengthwise direction, width direction, and thickness direction for positioning a plurality of cleaved and divided magnet fragments in an aligned state. The manufacturing device further includes a first pressing means that presses the plurality of magnet fragments to the thickness direction reference surface from the thickness direction of a magnet body to align them in the thickness direction, and a second pressing means that presses the plurality of magnet fragments to the width direction reference surface from the width direction of the magnet body to align them in the width direction. An operational axis line of a pressing part of at least one of the first and second pressing means is arranged to be tilted such that it approaches the lengthwise direction reference surface at the side that abuts the magnet fragments.
