ABSTRACT:
A heat-dissipating device and a motor structure. The heat-dissipating device has a outer frame provided with a seat, at least two rotors, a control unit and a stator. The rotors are respectively disposed on the seat. The control unit is disposed on the seat for controlling the rotation of the rotors. The stator for driving the rotors includes a plurality of silicon steel sheets or iron core embedded in the seat and a plurality of coils. Controlling the rotors with a single stator and a single control unit reduce the volume and cost of the heat-dissipating device.
