Alva Industries specializes in developing advanced slotless and ironless drone motors using FiberPrinting™ technology.

FiberPrinting™ innovation allows for improved thermal, mechanical, and electromagnetic properties, making their motors highly efficient and durable. Their products, such as the X60 high-thrust drone motor and ALTUS propulsion systems, are designed for mission-critical unmanned applications, offering reliability and safety features like dual-redundant communication and weatherproofing.

In the article; “A Beginner’s Guide to Torque Motors” Dr. Nicolas Giraudo, Chief Commercial Officer at Alva Industries explores the key features, advantages, and the rise of precision torque motors for advanced applications.

Key Features of Torque Motors

Torque motors are brushless, permanent magnet motors designed for high torque, typically used in direct drive systems where the load is directly attached to the rotor. Unlike traditional motors, torque motors are selected based on torque rather than power, making them ideal for applications requiring precise control and power at low speeds. Features include:

  • Frameless design: torque motors are comprised of a rotor and stator without mechanical housing, allowing easy integration into equipment.
  • High torque at low speed: they are designed for maximum torque output even when operating at low or no speed.
  • Compact and lightweight: the large bore relative to the outer diameter and low axial height, is ideal for tight spaces.
  • Brushless operation: this reduces maintenance costs and extends operational life.

Advantages of Torque Motors

Cost-effective direct drive – Eliminates the need for gears or belts, reducing material and assembly costs.

Low cogging – Virtually eliminates cogging through ironless or slotless electrical designs, enabling smoother motion.

High reliability – Fewer moving parts mean less wear and a longer operational lifespan.

Reduced vibration and noise – Direct drive systems reduce vibration and acoustic noise by removing intermediate components.

Typical Applications

  • Unmanned vehicles and drones
  • Surgical robots and prosthetics
  • Machine tools and semiconductor equipment
  • Exoskeletons and humanoid robotics
  • Reconnaissance pods and radar systems
  • Maritime thrusters and SAT-COM equipment

The Rise of Precision Torque Motors

Precision torque motors are designed for high-performance applications with extreme demands on torque and size. These motors often feature technologies like FiberPrinting™ to increase the winding density, ensuring superior dynamic performance. Precision torque motors are ideal for applications requiring ultra-compact designs with high torque output and minimal cogging such as drones.

Why Choose Torque Motors?

  • Unparalleled torque-to-weight ratio
  • Increased reliability with fewer mechanical components
  • Improved performance in critical systems

Torque motors, with their high torque capabilities and versatile design, are essential for industries that require precision and reliability. These solutions are ideal for UAVs used in industrial, defense, and aerospace sectors where performance and safety are paramount.
