    Abstract: Disclosed is a composite heat-dissipating system and its used fan guard which can impart a supercharging function to the heat-dissipating fans of the composite heat-dissipating system for efficient heat dissipation and reduces the noise generated when the heat-dissipating fans are operated. The fan guard includes a frame and a set of guard blades arranged inside and fixed onto an inner surface of the frame. The fan guard can be arranged upstream or downstream of the rotor blades of the heat-dissipating fans and assembled with the heat-dissipating fans in series or in parallel to supercharge the airflow out of the heat-dissipating fans.

    Abstract: Disclosed is a backup heat-dissipating system having a serial fan which can be assembled easily, fastly and conveniently, and can effectively eliminate the interference between fans and prevent the air leakage resulting from the failed fan unit. The backup heat-dissipating system includes a main frame, a first rotor device disposed in the main frame and including a first control device, and a second rotor device disposed in the main frame to be coupled with the first rotor device in series along an axial direction of the main frame and including a second control device. When the first rotor device fails, the first control device will output a signal to the second control device for driving the second rotor device to rotate at a relatively higher speed.

    Abstract: A motor having a magnetic bearing comprises a base formed with a bearing seat; a stator fixed to the base; a rotor provided with a rotation shaft and rotatable with respect to the stator by magnetic forces generated from excitation; a bearing fixed to the bearing seat of the base for receiving the rotation shaft of the rotor; and a magnetic element pair including a first element and a second element. The first element is telescopically interference-fitted on the rotation shaft, the second element is fixed relative to the bearing seat and lets the rotation shaft insert therethrough, and a magnetic force is generated between the first element and the second element. When the rotor rotates and an external force acts on the rotor in a direction, a magnetic force between the magnetic element pair counteracts the external force to achieve an axial positioning effect and avoid the contact wear.
