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.
