An improved elastic motor is disclosed having a constant torque characteristic. The motor utilizes a reel with elastic divided into unit lengths that are stretched to their maximum tension. Each unit length of the elastic is allowed to relax to its normal state while generating work in a process that will continue until the wheel is fully unwound. The present invention will ease design of mobile devices and the like by providing a power source having a predictable, constant, and stable output characteristic.
