The NEG'ATOR Constant Torque Spring motor is a prestressed strip of spring material which is formed into a coil nad stores on a small storage drum. The free end is then fastened to and backward woung onto a larger output drum this is the "winding" portion of the Constant Torque Spring's cycle. When the output drum is released, the spring will return to the storage drum to assume its natural curvature thus rotating the output drum and providing virtually constant torque.


  • NEGATOR spring motors are available from stock. These springs are made of Type 301 high-yield stainless steel and are supplied in coils for mounting on motor drums
  • Custom designs are available, use our design worksheet to specify your requirements and allow our Application Engineers provide you a design to meet your needs
  • Long deflections at nearly constant torque. Positive or limited negative gradients can be achieved.
  • Minimal intercoil friction and resultant hysteresis as is common in power springs.
  • Permits high working stresses due to residual stress resulting in very high energy storage.
  • Provides rotary motion directly from output drum or linear displacement via cable and spool arrangements.
