Optimized design research on adjustable-speed permanent magnet coupling

Based on a 3D finite element model, one adjustable speed permanent magnet coupling(ASPMC) was studied. By analyzing finite element simulation results, some basic conclusions for adjustable-speed permanent magnet couplings´ design and optimization have been presented. Simulate and analyze the electromagnetic field and eddy distributions of prototype at rated operating station. When the prototype´s performance is optimum, confirm the permanent magnet´s thickness and width, the copper disc´s thickness and outer diameter. Besides, the relationship and regularity between the outer diameter of the coupling and transmitted power has been proposed. The prototype´s torque transmission capability over the full range of slip speed for different airgap settings and process for speed adjustment are given. Manufacture a prototype and build a experimental platform. Through the experimental test, verify the reasonability of the prototype´s design and the applicability of the optimizing design method.
