1results about How to "Reduce starting power" patented technology

The application relates to a permanent magnet coupler for energy saving of an air compressor and a torque self-adaptive adjusting method thereof, and relates to the technical field of couplers, which comprises a driving rotor, a driven rotor, the driven rotor being coaxial with the driving rotor, copper rings, the copper rings being two, the two copper rings being rotationally sleeved on the mutually close end portions of the driving rotor and the driven rotor, a plurality of connecting rods, the plurality of connecting rods being circumferentially arranged between the two copper rings, the two ends of the plurality of connecting rods being connected with the two copper rings respectively, and the plurality of connecting rods and the two copper rings jointly forming a frame body of the coupler, square shafts, the end portions of the driving rotor and the driven rotor being provided with square grooves, and the two ends of the square shafts being embedded in the two square grooves respectively, slip rings, the slip rings being two, the two slip rings being symmetrically and slidably sleeved on the two ends of the square shafts along the length direction, and the mutually close sides of the two slip rings being provided with permanent magnets respectively. The application has the advantages that energy can be saved when the transmission torque of the air compressor is adjusted.
