Alva Industries Expands SlimTorq™ Portfolio with New STM-190-35 Motor Size
Trondheim, Norway – 9 April, 2026 – Alva Industries (Alva), a manufacturer of frameless motors and the creator of FiberPrinting™ technology,today announced the launch of SlimTorq™ STM-190-35, a new larger size in its SlimTorq™ frameless, slotless motor portfolio. The STM-190-35 expands the STM range with increased torque capability and precision, enabling demanding direct-drive applications where performance, compactness, and design flexibility are critical.

The STM-190-35 is designed for high-precision direct-drive systems such as electro-optical platforms, gimbals, robotics, and other motion-critical applications. With a favorable inner-to-outer diameter ratio and a compact axial length, the motor supports space-efficient system designs without compromising torque density or control performance.
To support system-level design and evaluation, the STM-190-35 is fully supported in Alva’s TorqStudio design and simulation platform. TorqStudio allows engineers to evaluate motor performance, explore winding options, and optimize motor selection early in the design process based on application-specific requirements.
“With the STM-190-35, we extend the SlimTorq™ range to address applications that require higher torque in a compact frameless format,” said Nicolas Giraudo, CCO at Alva Industries. “This new size gives system designers more freedom to optimize performance and mechanical integration, especially in direct-drive solutions where precision and smooth motion are essential.”
The addition of the STM-190-35 brings the SlimTorq™ STM portfolio to nine available motor sizes, spanning different outer diameters and lengths. Each size can be configured with multiple inner diameter options, winding patterns, and custom configurations, allowing engineers to tailor the motor to their specific application requirements.
Like all SlimTorq™ motors, the STM-190-35 is manufactured using Alva’s patented FiberPrinting™ technology, delivering ironless, slotless windings with high copper fill factor and zero cogging. The motor is available with multiple winding options, different terminal block designs, and optional temperature sensors and Hall sensors, supporting precise control and system-level optimization. Detailed specifications and available configurations for the SlimTorq™ STM-190-35 can be found in the SlimTorq™ product catalog.
