ALVA has also introduced a new 3-phase Hall-effect sensor option, available across the entire SlimTorq™ lineup. These sensors feature open-drain output, a built-in 1.2kΩ pull-up resistor, and 5VDC supply voltage, enabling reliable and straightforward integration for applications requiring commutation or simple speed and position feedback.

SlimTorq™ is the thinnest and lightest torque motor range available on the market ideal for high-precision and high-speed applications on land, sea, air and space. SlimTorq™ motors are manufactured by Alva’s revolutionary FiberPrinting™ technology which enables ironless and slotless motor windings with up to 60% copper fill factor, setting a new standard in precision, torque density and adaptability.
Applications for SlimTorq™ motors include:
- High Precision Gimbals
- Medical Devices & Surgical Robots
- Defense & SatCom
- Light Robotics
- Marine Propulsion
- Metrology
- Semiconductor
“FiberPrinting™ allows us to break through the limitations of conventional motor manufacturing,” said Nicolas Giraudo, Chief Commercial Officer at ALVA Industries. “With SlimTorq™, our customers benefit from a unique combination of slim design, high torque density, linearity and scalability - all while reducing weight and optimizing heat dissipation.”
