Abstract: A driving device configured to drive a rotary body includes a motor assembly and a plurality of first magnets disposed on the rotary body along a circumferential direction thereof. Sides of the magnets facing the motor assembly form a plurality of magnetic poles. Upon rotation of the motor assembly, the magnets is driven by magnetic interaction between the motor assembly and the magnetic member to rotate to drive the rotary body to rotate. The present invention also provides a bladeless fan including this driving device.
