Customized core: not only adaptation, but also performance upgrade

1. All parameters are customized on demand to accurately match the working conditions

• Stiffness customization: high static-low dynamic stiffness characteristics can be customized, effectively solving the contradiction between low natural frequency and high bearing capacity in the field of low-frequency vibration isolation, and can also customize the gradient stiffness of positive slope and negative slope according to the needs to adapt to different shock absorption and support needs.
• Stroke and output customization: The stroke covers 40-350mm, the output range can be flexibly adjusted from 15N to 110N or more, supports series and parallel combination design, provides multiple times the output in large load scenarios, realizes the constant force output of the whole stroke, and avoids the disadvantages of traditional mechanical spring output changing with the amount of deformation;
• Environmental adaptation customization: For special working conditions such as high temperature, low temperature, vacuum, strong corrosion and magnetic field sensitivity, non-magnetic high-strength materials (such as non-magnetic stainless steel, titanium alloy, etc.) are preferred, the structural design is optimized, magnetic residues are eliminated, the effect of temperature sensitivity is reduced, and the stable operation can be achieved in extreme environments, and complex magnetic field-sensitive scenarios can be adapted without additional protection.
• Structure customization: The integrated structure of mover and stator can be customized, with guide bearings or adapted to the customer's existing equipment structure, compact in size, easy to integrate into space-constrained precision modules, without additional guide rails, simplifying the overall design of the equipment.

2. Blessing of core advantages, surpassing traditional solutions

• Non-magnetic and maintenance-free: Made of completely non-magnetic materials, without any magnetic field interference or magnetic residue, it is perfectly suitable for magnetic field-sensitive scenarios such as medical imaging, semiconductors, and precision electronics. The core components have no physical contact, no mechanical friction, no wear, longer theoretical service life, no need for regular lubrication and maintenance, and greatly reduce the maintenance cost of the whole life cycle of the equipment.
• Constant force efficient response: the output within the stroke range, no hysteresis, the response speed is only affected by mechanical inertia, which can achieve instant response, effectively improve the smoothness of equipment operation and control accuracy, avoid additional interference, and optimize system energy efficiency;
