ABSTRACT:
An improved elastic motor is disclosed having a constant torque characteristic. The motor utilizes a reel with elastic stretched to its maximum tension. Each unit length of the elastic is allowed to relax back 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 and stable output characteristic.
