摘要
A rotor (85) assembly for a permanent magnet motor includes a set of laminations forming a rotor body, each lamination having a first magnet slot (97) therein. A generally rectangular permanent magnet is disposed in the magnet slot (97), the magnet slot (97) of each lamination being shaped so as to receive the rectangular permanent magnet through all the skewed laminations with a minimum air gap. A method of making an assembly such as a rotor (85) includes the steps of providing an assembly body made of ferromagnetic material defining at least one magnet slot (97) therein. The slot is at least partially filled with a mixture of magnetizable particles in a binder. The mixture is compressed and then cured to bond the magnetizable particles together in the slot (97) and the bonded part icles are then magnetized in the slot (97) to form a magnet in situ in the slot (97) without an air gap.
