| Summary: | In this paper, a long stroke moving secondary permanent magnet linear eddy current brake is proposed. Without exciting coils, the permanent magnet eddy current brake possesses the advantage of saving copper and better reliability. The topology and operating principle are presented. The mathematical model was derived with the layer theory. The braking force characteristic was analyzed using the finite element method. The structural parameters of the long stroke moving secondary permanent magnet linear eddy current brake were studied by referring the design progress of the other types of eddy current brakes. Finally, a prototype of long stroke moving secondary permanent magnet linear eddy current brake was built and tested, and the experimental result verifies the correctness of the above analysis. |
