FIG. 7 is a schematic view illustrating an application in which the present invention is combined with a spinner bike 8b. When the operator treads pedals of the spinner bike 8b, the flywheel 2 is driven to rotate, and a lifting device 9 that is arranged in a chassis of the spinner bike 8b is controlled by the processing unit 61 to drive the spinner bike 8b to oscillate for exhibiting uphill or downhill to thereby generate simulation for a slope. Under the control of the permanent-magnet synchronous motor driving and resistance control system 100 (or 100a and 100b) according to the present invention, the permanent-magnet synchronous motor 3 may be operated in the first operation mode or the second operation mode. The spinner bike 8b of this application may be replaced by a known bicycle trainer.
FIG. 8A is a schematic view showing a substitute example of the present invention combining a permanent-magnet synchronous motor with a flywheel of an exercise bicycle. FIG. 8B is a schematic view illustrating that shown in FIG. 8A with a sensor support removed. In the permanent-magnet synchronous motor driving and resistance control system 100c of the instant embodiment, constituent components are generally similar to those of the embodiment shown in FIGS. 1A and 1B, and a difference is that the instant embodiment further comprises at least one electricity generation winding 312. The electricity generation winding 312 is wound, together with the stator windings 311, around magnetic poles of the stator 31.
