Claim 0:
1. A resistance device, comprising:
a first rotating assembly rotatable about an axis and including a first rotating member that is conductive;
a second rotating assembly including a second rotating member spaced from said first rotating member, and a plurality of magnets arranged on said second rotating member at intervals around the axis, N and S poles of said magnets being alternately arranged on said second rotating member and facing said first rotating member, said first rotating member being influenced by said magnets to generate eddy currents during rotation of said first rotating assembly and said second rotating assembly relative to each other in order to brake rotation of said first rotating assembly and said second rotating assembly relative to each other;
a transmission unit connected to one of said first rotating assembly and said second rotating assembly for driving rotation of said one of said first rotating assembly and said second rotating assembly; and
a drive unit connected to another one of said first rotating assembly and said second rotating assembly, said drive unit being configured to receive a control signal and being configured to drive rotation of said another one of said first rotating assembly and said second rotating assembly according to the received control signal;
wherein the eddy currents generated by said first rotating member during rotation of said first rotating assembly and said second rotating assembly relative to each other provide resistance to said transmission unit;
wherein said first rotating member is a conductive disc having one surface facing said magnets; and
wherein said first rotating assembly further includes a magnetic conductive disc located on another surface of said first rotating member that is opposite to said magnets.
