The Flexible Link (FX Series) represents a groundbreaking innovation in the field of miniature drives. The device seamlessly integrates a ball screw with a fixed support unit, providing exceptional flexibility to fix the screw (either precision or rolled ball screws) very compactly on the outgoing shaft (with a length of 15 or 20mm) from a stepper motor or servo motor. The FX Series achieves a dramatic reduction in connection length with less than half that of a conventional coupling design, while maintaining the same modular flexibility. The FX is designed for mounting on NEMA 10 and NEMA11 servo and stepper motors.

Despite its compact size, the FX series is capable of a speed of up to 3,000 rpm and an axial load limit of up to 80 N.

The housing is made of black anodized aluminium and ensures robustness and resilience

WORKING DEMO:

At the booth of Dynetics (Hal 4-490) the supplier demonstrates the performances of this Multi-Axis Control product in an active alignment system completed with their EtherCAT 5-Phase Stepper Driver (STP-K5241A) with Position Compensation.

This opens up broad adaptability for machinery builders looking for seamless scalability across multiple axes.

Supplier Nidec (distributed by Dynetics) announced several impressive successes for its hybrid stepper motors, including a reliable magnet replacement and the realization of a more compact size.

China has introduced export restrictions on neodymium magnets and related rare earth elements, requiring a mandatory government license for export since April 2025. This measure will cause significant disruptions to the global supply chain, leading to longer delivery times, potential shortages of high-power magnets, and higher costs worldwide. In addition, shipments containing certain heavy rare earths require a mandatory, individual approval process, which can further extend delivery times.

To mitigate the consequences of the risks of these export restrictions, the supplier is prompting Nidec to implement robust compliance solutions for its products.

Supplier Nidec reported that it completed its tests on the stepper motors with a new neodymium magnet that does not contain dysprosium (Dy) and gadolinium (Gd) and concluded that this new material did not show any significant change in performance compared to the traditional stepper motors. This success allows the supplier to expand the list of permitted uses, making the supplier less dependent on available sources and avoiding the impact of Chinese export regulations on magnets,

Thanks to the optimized design of the rotor, the manufacturer Nidec has succeeded in realizing a more compact size of the motor. Compared to comparable stepper motors in industry, the stepper motors of the KV42 and KF42 enable significantly higher performance in a more compact package. Instead of the previous length of 48 mm, these motors have a length of only 42 mm. The motors with the previous length of 42mm will be reduced to 39mm, etc. The KF42 even achieves a higher torque.

Other benefits include higher limiting torque, more holding torque, high speed, minimal noise, precision windings, high rigidity, and improved motor dynamics. According to the manufacturer, this means that the engines of the KV42 and KF42 series have the highest power density in their class. The motors are manufactured in versions with plugs or free cable ends. Customizations are possible at the customer's request.

Shaft motors with contactless magnetic counterweight

When shaft motors are used vertically, a counterweight is required to compensate for the gravitational effect. Without a counterweight, the motor shaft would fall down in the de-energized state. In conventional designs, the spring counterweight is a critical component because the spring ages over time and requires special attention to maintenance. A new, maintenance-free counterweight called gLESS uses magnetic force and enables uniform movement. The counterweight realizes a stable movement and is maintenance-freeCompared to the spring counterweight, the magnetic counterweight offers the following advantages:

• The "spring constant" does not change even after many years of use.
• The shaft does not fall down without current.
• Almost no scattering of magnetic flux
• Compact solution in combination with the manufacturer's shaft motor.
• Constant balancing force.
• Non-contact function ensures that there is no maintenance.

The gLess series is available in 3 sizes in diameter (Ø13; Ø18; Ø18mm), and covers force ranges of 2.66; 6.1 and 19.6N, with a working stroke of 40 mm. The gLESS components are designed as a non-contact solution and can be mounted very close to the shaft motor.

NEW: Based on the scale-free linear motor SX060, manufacturer NPM has launched a complete linear motor unit on the market, which is equipped with gLESS counterweight. The linear motor does not require an external encoder and has almost no magnetic leakage fluxes, which means that compact applications with more than one motor with a distance of only 9mm can be realized
