Summary:The motor system (101) comprises a driving shaft (130) for driving a load (120) to rotate, and a bearingless motor (170) and a radial magnetic bearing (180) which are arranged side by side along the axial direction of the driving shaft (130). The radial load of the drive shaft (130) is supported in a non-contact manner by a bearingless motor (170) and a radial magnetic bearing (180). A thrust magnetic bearing (150) is arranged between the bearingless motor (170) and the radial magnetic bearing (180). 电动机系统(101)包括驱动负载(120)旋转的驱动轴(130)、以及沿着驱动轴(130)的轴向并排设置的无轴承电机(170)及径向磁轴承(180)。驱动轴(130)的径向载荷由无轴承电机(170)以及径向磁轴承(180)以非接触的方式支承。在无轴承电机(170)与径向磁轴承(180)之间布置有推力磁轴承(150)。
