Abstract

　本発明の洗濯機は、水槽と、前記水槽に収容された負荷を回転駆動するモータとを備え、洗い行程、すすぎ行程及び脱水行程を含む洗濯運転を実施する。前記モータは、ステータコイルを有するステータと、保磁力の高い永久磁石からなる第１のマグネット、及び前記第１のマグネットより保磁力が低く磁束の変更が容易な永久磁石からなる第２のマグネットを含むロータマグネットを有するロータと、を備える。前記洗濯運転が洗い行程のとき、前記第２のマグネットは、前記ステータに対して作用する前記ロータマグネットの磁束が増加するように磁化され、前記洗濯運転が脱水行程のとき、前記第２のマグネットは、前記ステータに対して作用する前記ロータマグネットの磁束が前記洗い行程のときよりも減少するように磁化される。
