User:Derwood B. Harlow/Spring motor

The basic Spring Motor is a simple machine containing a spring or springs that can be wound up. By winding a spring it creates torque under pressure. This is caused by the material make up of the spring. For example (spring steel) To use this wound spring as a motor, a connection to a shaft or axle is required. The spring is then released and the torque created by the tension is directed to an axle, or point of use. The mechanical gear, pulleys, belts etc release the spring until it is unwound. It is stored energy over a distance and time, depending on the makeup of the spring and how tightly it was wound. See Mechanisms and mechanical devices sourcebook Neil Sclater, Nicholas P.
