Motor Springs

motor springs

European Springs also design and manufacture Motor Springs that are constructed using the design and structure of a specially stressed constant force spring. This design means the spring can provide rotational energy from the attached shaft, locked with a catch, pin or housing edge. This specific design of motor springs allows for an average 10-20 spring force turn.

Sometimes, more torque is required than what a standard singular motor spring can provide, and in this case, several motor springs together can make up the optimum performance needed. Our motor springs are made of stainless steel and have a long fatigue life dependent on spring size and maximum torque output on number of operations. Springs placed in housing with the outer hook located around a pin have the smallest internal diameter. They can be places in larger housing but the applied force will decrease but it is possible to slightly increase the diameter of the inner coil for placement on a larger shaft. However, if more torque is required and more springs are added, our Motor springs are covered in a protective nylon band to minimize friction, but we also advise lubricating the springs when assembling.

Since 1948 we have been manufacturing springs of a superior quality and supply to many industries across the world. We are committed to providing our customers with an excellent service so if you require more information about our motor springs or any of our other products please get in touch and we can discuss your project's requirements.
