Treadmill which can be driven in both directions

Abstract

Disclosed is a treadmill including a walking belt driven forward and backward and when changed from a forward moving mode to a backward moving mode, which can re-adjust a driving speed of a servomotor and an inclination angle of the walking belt. The treadmill according to the present invention includes: selector for driving the walking belt backward; the selector for driving the servomotor backward by receiving a command of the selector for driving the walking belt backward; when the servomotor is driven backward, a selector for selecting the velocity of the servomotor to input the selected velocity data to the servomotor; a selector for selecting an inclination angle of the walking belt to drive an inclination angle motor based upon the selected inclination angle; and a maintainer for maintaining the tension of the walking belt.
