IKO’s NT Nano Linear Series

IKO’s NT Nano Linear Series utilizes an integrated direct drive linear motor and a high-resolution linear encoder for exceptional positioning accuracy. Additionally, powerful built-in neodymium magnets are used, providing high drive force. This enables high speeds, high accelerations, and decelerations, resulting in an exceptionally responsive system.

The linear stage is designed to optimize positioning accuracy and responsiveness. Here’s how it works: the magnets of the linear motor and the optical linear encoder scale are mounted on the moving table. The motor coils and optical linear encoder readhead are attached to the stationary part. This eliminates trailing cables that could impede movement, cause wear, or generate unwanted particles that might otherwise contaminate a clean environment.

The benefits of this design directly translate into measurable performance. The specifications below show exactly what the series offers technically.

What are the specifications?

The NT Nano Linear Series was developed with attention to detail and precision. The main features are listed below.

1. Positioning Repeatability: Guarantees a repeatability with a maximum deviation of $\pm 0.5 \mu\text{m}$ or $\pm 0.1 \mu\text{m}$.
2. Running Accuracy: Ensures movement with a maximum deviation of $\leq 1 \mu\text{m}$.
3. Resolution (Step Size): Allows incremental movements adjustable from $0.5 \mu\text{m}$ to $0.01 \mu\text{m}$.
4. Angular Accuracy: Limits the angular deviation during movement to 5 arcseconds or less.
5. Maximum Thrust: Delivers the power for rapid acceleration, up to $36 \text{N}$ for a single axis and $70 \text{N}$ for multi-axis configurations.
6. Dimensions (Compact Model): Specifically designed for tight spaces, with a width of $38 \text{ mm}$ and a profile height of $11 \text{ mm}$.

Although the specifications are impressive, the true added value comes to life thanks to the collaboration between IKO and VARIODRIVE.

Collaboration between VARIODRIVE and IKO

The relationship between IKO and VARIODRIVE is a perfect example of a strategic partnership. IKO is the manufacturer of the advanced mechanical components, such as the NT Nano Linear positioning stage. They provide the physical foundation for precise movement.

VARIODRIVE complements this by transforming these components into a complete, functional solution. They add their expertise in mechatronics, which means they select and integrate the correct motors, control electronics, and software. As a result, the customer does not receive separate components but a fully tested and optimized motion system that is immediately ready for use in their machine. In essence, IKO supplies the hardware, and VARIODRIVE provides the intelligent control that brings this hardware to life.
