The SPIR'ATOR prestressed spiral Power Spring is produced by reverse winding a NEG'ATOR on an arbor and enclosing it in a case. Rotational energy can be obtained from either the arbor or case or, when linear motion is required, through use of a pulley and cable attachement.
The unique design of this encapsulated Power Spring yields a compact power source which operates with higher working stress and can provide more than twice as many revolutions as a conventional power spring in the same size case. With torque and deflection being equal, a SPIR'ATOR generally requires 20% less space than a power spring. Most importantly, this power package creates a low torque gradient.
