Spiral Torsion Springs

Spiral torsion springs are produced from flat steel and are characterized by the symmetric spacing between coils. A spiral torsion spring will exert a rotational torque, usually through 360° rotation or less. The torque curve of a spiral torsion spring is linear to the degree of rotation. Spiral torsion springs are used in brush motors and in certain applications where a short rotation is required.
