The application provides a rotor slot wedge structure of a magnetically conductive and electrically conductive alloy material, and belongs to the technical field of double-shaft excited electric machines. The magnetically conductive and electrically conductive alloy is adopted, so that the rotor slot wedge structure has both electrical conductivity and magnetic conductivity, can guarantee the damping and oscillation suppression capability of the double-shaft excited electric machine, and can also run asynchronously at a large slip. The inertia support capability of the double-shaft excited electric machine is improved, and the frequency stability of the power system is guaranteed. Compared with a traditional slot wedge structure, a cross-shaped shallow groove is arranged on the surface of the slot wedge, so that the eddy current path can be blocked and the eddy current loss of the slot wedge can be reduced when the double-shaft excited electric machine runs asynchronously at a high slip. In addition, the shallow groove also increases the contact area between the surface of the slot wedge and the air in the air gap, and improves the heat dissipation capability. The double-ventilation groove setting of the air outlet of the slot wedge and the unequal outlet diameter setting are beneficial to balancing the air flow in each radial ventilation groove, reducing the axial thermal imbalance of the rotor winding, and reducing the insulation thermal stress.

This invention discloses a backflow suppression device and an anti-backflow fan and refrigerator including the same. The backflow suppression device is used to suppress the backflow of gas from the air inlet of the fan to the outside of the fan. It includes: a flow-suppressing part, which is arranged around the outer edge of the air inlet, with one side of the flow-suppressing part rotatably connected to the outer edge of the air inlet, and the other side of the flow-suppressing part extending towards the axis of the air inlet, and the flow-suppressing part being used to rotate around the outer edge of the air inlet; and a limiting part, which is arranged around the outer edge of the air inlet, and the limiting part being used to restrict the rotation of the flow-suppressing part towards the outside of the fan. When gas backflows from the air inlet, the flow-suppressing part rotates towards the limiting part; when air enters the air inlet, the flow-suppressing part rotates towards the impeller of the fan. The flow-suppressing part can block the backflow generated in the positive pressure zone, thereby reducing eddies and the noise generated by eddies. It reduces repetitive work, thereby improving the efficiency of the fan and reducing energy consumption.
