Claim 6:
7. The driving and resistance control system according to claim 6, wherein the resistance controller comprises:
a first rectifier and filter circuit connected to the plurality of stator windings of the permanent-magnet synchronous motor to filter and rectify the generation voltage into a DC voltage; and
a PWM control circuit electrically connected with the first rectifier and filter and the electromagnetic resistance generation device, and is operable to generate, according to the DC voltage, the PWM control signal to control the electromagnetic field intensity of the electromagnetic resistance generation device, so as to generate an eddy-current resisting force on the external rotor during rotation of the external rotor to thereby change the resisting force acting on the flywheel.
