Claim 0:
1. A motor brake device of an exercise apparatus, comprising:
a motor having a motor shaft;
a brake device having a rotating disc coaxially connected to the motor shaft and a magnetic brake mechanism, the rotating disc being an electrical conductor, the magnetic brake mechanism configured to apply a drag force against rotation of the conductive disc, the magnetic brake mechanism having at least one magnetic portion; and
a lifting device configured to drive the magnetic brake mechanism to move between a first position where the magnetic portion is located close to the rotating disc and a second position where the magnetic portion is located away from the rotating disc;
wherein a height of a gravity center of the magnetic brake mechanism at the second position is higher than the height the gravity center of the magnetic brake mechanism at the first position, when there is no electric power supplied to the exercise apparatus, the magnetic brake mechanism will move downward to the first position to stop rotation of the motor shaft by gravity due to potential difference between the second position and the first position.
