A new larger size in its SlimTorq frameless, slotless motor portfolio
Alva Industries, manufacturers of frameless motors and creator of FiberPrinting technology, has launched 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, facilitating demanding direct-drive applications where performance, compactness, and design flexibility are critical
The STM-190-35 has been developed for high-precision direct-drive systems, such as electro-optical platforms, gimbals, robotics, and other motion-critical applications. With an inner-to-outer diameter ratio and a compact axial length, the motor enables space-efficient system designs without compromising torque density or control performance.
To support system-level design and evaluation, the STM-190-35 is supported in Alva’s TorqStudio design and simulation platform. Engineers can use TorqStudio to evaluate motor performance, explore winding options, and optimise motor selection early in the design process based on application-specific requirements.
Nicolas Giraudo, CCO at Alva, said, “With the STM-190-35, we extend the SlimTorq range to address applications that require higher torque in a compact frameless format. This new size gives system designers more freedom to optimise performance and mechanical integration, especially in direct-drive solutions where precision and smooth motion are essential.”
With the STM-190-35, the SlimTorq STM portfolio has nine available motor sizes, spanning different outer diameters and lengths. Each size is configurable with multiple diameter options, winding patterns, and custom configurations so engineers can tailor the motor to their specific application requirements.
The STM-190-35 has been manufactured using Alva’s FiberPrinting technology, providing 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, enabling precise control and system-level optimisation.
