Abstract: An electric treadmill includes an endless belt, a motor and a motor driving circuit. The motor driving circuit is operable to control electric current flow from a positive electrode through the motor to a negative electrode to drive the motor. The motor driving circuit has a power resistor and a switch element connected in series between the positive electrode and the negative electrode. When the motor driving circuit receives power from an external power source, the switch element automatically switches to an open state so that the power resistor is inactive. When the motor driving circuit does not receive power from the external power source, the switch element automatically switches to a closed state, and the power resistor becomes a load for consuming power generated by the motor when the endless belt is driven by an external force, such that the motor operates to resist rotation of the endless belt.

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.
