Depending on requirements, where there is a requirement to obtain several turns from a torsion spring, motor springs can be used instead.
Motor springs are locked to a shaft with a catch, and to a pin or housing edge. This design can give 10-20 turns of spring force.
If you need more torque than what one motor spring can perform, just use several motor springs next to each other.
The motor springs are often represented in the electric power industry in for example distribution plants, usually manufactured in stainless steel.
