Magnetic suspension centrifugal fan

The utility model relates to the field of fans, in particular to a magnetic suspension centrifugal fan. The magnetic suspension centrifugal fan comprises centrifugal fan blades and a driving motor used for driving the centrifugal fan blades to rotate. The driving motor is mounted in a hub center cavity of the centrifugal fan blade; the centrifugal fan is characterized in that the driving motor adopts an outer rotor motor and comprises an outer rotor shell and a motor stator, and the outer rotor shell is connected with the centrifugal fan blades to realize circumferential linkage; and a rotor shaft core is arranged at the center of the outer rotor shell and extends into a magnetic suspension bearing in the motor stator. The magnetic suspension centrifugal fan greatly reduces noise and vibration generated by mechanical friction. 本实用新型涉及风机领域，尤其涉及一种磁悬浮离心风机。磁悬浮离心风机，包括离心风叶，以及用于驱动所述离心风叶旋转的驱动电机；驱动电机安装于离心风叶的轮毂中心腔内；其特征在于：所述驱动电机采用外转子电机，包括外转子壳体和电机定子，外转子壳体与离心风叶相连实现周向联动；外转子壳体的中心处设置有转子轴芯伸入电机定子内的磁悬浮轴承内。该磁悬浮离心风机大幅降低了机械摩擦产生的噪声
