摘要： A motor suited for use in a direct drive laundry machine. The described motor has a stator core including an annular ring with an inner diameter between 120 mm and 250 mm, a radial width between 5 mm and 15 mm, and 24 or 27 stator poles projecting outward from the annular ring a distance of between 15 mm and 40 mm. Each stator pole is associated with one of three phase windings. A rotor for the motor has inwardly facing permanent magnet poles whereby the ratio of rotor poles to stator poles is 4:3.

摘要： A magnet element (37) and a method of its manufacture for assembly into a rotor (38), the magnet element (37) having magnetic domains aligned anisotropically to form a domain alignment pattern (42), wherein the magnetic domain alignment pattern (42) in the magnet element (37) has an orientation that varies substantially continuously across at least part of the magnet element (37) between its lateral edges from at least partially radial to at least partially tangential.
