ALVA Industries to Showcase Frameless Motors and Live Demonstrations at SPS 2026

ALVA will showcase demonstrations highlighting how frameless motors can be integrated into compact, high-performance motion systems.

Nabtesco: Super-Short Actuator - Developed in collaboration with Nabtesco, the new Super-Short Actuator will make its debut at SPS 2026. Combining ALVA's frameless motor technology with Nabtesco's precision gearing, the actuator is designed to deliver high performance in a significantly more compact package.

The design achieves approximately 30% reductions in both length and weight compared with comparable actuator solutions. The system can also be paired with a motor controller developed by adcos, part of the Nabtesco Group.

Siboni and FLUX: Integrated Direct-Drive Solution - Developed in collaboration with Siboni, another demonstration features ALVA's SlimTorq STM-130-27-M motor integrated into a framed direct-drive assembly with a FLUX inductive encoder. The demonstration illustrates how frameless motor technology can be integrated into complete motion systems for applications including gimbals, optronics, exoskeletons, and semiconductor equipment.

ALVA Demo: Slotted vs Slotless Motor Technologies - Visitors can experience ALVA's slotted vs. slotless motor demonstration, offering a hands-on comparison of the two technologies. By interacting directly with both motors, visitors can feel the difference in cogging torque, explore their holding torque capabilities, and see how slotless technology enables smooth motion and precise control.

Solo Motor Controllers: Haptic Feedback Simulator - Developed in collaboration with Solo Motor Controllers, the final demonstration features a haptic feedback simulator that compares slotted and slotless motor technologies in the context of automotive applications. The simulator illustrates how differences in cogging torque can affect motor behaviour, highlighting the benefits of zero cogging torque for smooth and precise motion.

Visitors can experience the differences between the two technologies and gain a clearer understanding of their impact on real-world applications.

Visitors will also be able to explore ALVA's SlimTorq and GearTorq frameless motor series, both manufactured using the company's proprietary FiberPrinting technology.

SlimTorq is designed for applications requiring smooth, precise motion, offering zero cogging, high torque density and a compact, lightweight design. Its large through-hole makes it particularly suitable for direct-drive applications such as gimbals, robotics, and semiconductor equipment.

GearTorq, ALVA's newest frameless motor series is developed specifically for geared applications and actuator systems. With its compact outer diameter and large through-hole, GearTorq allows gear components to be integrated within the motor, delivering high torque density and high peak torque without torque saturation. The series is available in 39 mm, 64 mm, and 88 mm outer diameters, with multiple winding options and further customisation possible.

Visitors can experience TorqStudio, ALVA's online platform for motor creation and analysis, through live demonstrations at the booth. The platform enables engineers to design, customise, and evaluate motor configurations based on their specific application requirements.
