Claims

1. A double-shaft extension permanent magnet motor direct connection oil-free scroll compressor, characterized in that, It includes a dual-shaft extension motor, a moving plate assembly, and a stationary plate assembly. The dual-shaft extension motor is fixedly mounted on a bracket, and the stationary plate assembly is fixedly mounted on the end face of the bracket. The two shaft ends of the dual-shaft extension motor have a first shaft end that serves as the power input end and is connected to the moving plate assembly for transmission, and a second shaft end that is fixedly connected to a fan wheel. The fan wheel guides cooling air to a designated position through an air duct. During the movement of the moving plate assembly, the volume between it and the stationary plate assembly changes, compressing the gas and causing it to be discharged from the stationary plate assembly. The bracket is designed with a motor positioning stop to keep the center line of the dual-shaft extension motor and the center of the bracket at the same center. The stationary plate assembly is also equipped with a positioning pin to keep the center of the stationary plate and the center of the bracket at the same center.

2. The dual shaft permanent magnet motor direct-coupled oil-free scroll compressor of claim 1, wherein: The air duct includes a fan cover, a guide channel, and a heat dissipation air duct, which are arranged outside the fan wheel. One end of the fan cover is connected to the guide channel, and the other end of the guide channel away from the fan cover is connected to the heat dissipation air duct.

3. The direct-coupled oil-free scroll compressor of a two-shaft extension permanent magnet motor of claim 2, characterized in that: The inlet and outlet sections of the guide channel are perpendicular to each other, and the outlet section of the guide channel is arranged parallel to the inlet section of the heat dissipation duct.

4. The dual shaft permanent magnet motor direct-coupled oil-free scroll compressor of claim 2, wherein: The heat dissipation duct is fixedly installed on one side of the bracket. The stationary plate assembly is integrated with the heat dissipation duct, and multiple heat dissipation fins are arranged on the stationary plate assembly. The heat dissipation fins are located in the inner cavity of the heat dissipation duct. Multiple heat dissipation fins are also arranged on the end face of the moving plate assembly near the heat dissipation duct. The heat dissipation fins are arranged perpendicular to the plate surface.

5. The direct-coupled oil-free scroll compressor of a two-shaft permanent magnet motor of claim 4, wherein: The designated location is a position where air can be blown onto the heat dissipation fins of both the stationary disk assembly and the moving disk assembly simultaneously, and the cooling air from the guide channel outlet is directed onto the heat dissipation fins of both the stationary disk assembly and the moving disk assembly.
