Abstract
An electric treadmill includes a treadmill frame, an endless belt, a motor coupled to the endless belt for driving the endless belt to rotate, a brake device and a lifting device. The brake device has a rotating disc coaxially fixed to a motor shaft of the motor and a magnetic brake mechanism. The magnetic brake mechanism has at least one magnetic portion for applying a drag force against rotation of the rotating disc. The lifting device is operable 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. When there is no electric power supplied to the electric treadmill, the magnetic brake mechanism will automatically move to the first position due to gravity to stop rotation of the endless belt.
