Abstract
A method of manufacturing a magnet segment of a field pole magnet body includes cleaving a magnet material at a plurality of cleavage target regions arranged with an interval in a longitudinal direction of the magnet material. The cleavage process includes cleaving the magnet material sequentially from the cleavage target region closer to one side edge of the longitudinal direction of the magnet material, wherein a notch is formed in each of the plurality of cleavage target regions of the magnet material such that a depth of the notch closer to the one side edge becomes deeper.
