Flat spiral springs are also known as spiral torsion, clock springs or brush springs. They are characterized by the requirement that the coil contact is minimized during operation. ... Power springs (also known as Recoil springs or Motor springs) store and release rotational energy in the form of torque.

How do flat spiral springs work?

A flat spiral spring is made by winding a band-shaped material so that its central line forms a spiral on a plane, and acts as a spring by applying an external force to one end of the spring. ... The shape is selected according to the spring's load characteristics and application.

What is the use of spiral spring?
