Description
technical field [0001] The invention relates to an AC permanent magnet synchronous electric spindle, in particular to a dustproof and sealed AC permanent magnet synchronous electric spindle. Background technique [0002] When designing the electric spindle, it must be considered that dust and other dirt from the outside enter the interior of the electric spindle along the axial direction from the output end of the rotating shaft of the electric spindle, polluting the internal environment of the electric spindle. The current practice is to use an "0" ring seal at the front end of the electric spindle. Disadvantages of this method: On the one hand, it is a contact seal. When the speed is relatively high, the wear is serious, and the "0" ring seal is easy to fail; on the other hand, if the high-performance wear-resistant "0" type is selected Circle, the cost is higher. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of ...
