Alva Industries is a leading developer of next-generation motors for UAVs (unmanned aerial vehicles) and drones. Our ironless and slotless motors are designed for mission-critical applications, providing superior performance without compromising on reliability or durability.

Slotless motor winding

Our drone propulsion products are based on our proprietary industry-leading FiberPrinting technology, which allows us to rapidly design and manufacture ironless windings for any electric motor or generator. FiberPrinting enables technical and composite fibers to be combined in order to enhance the thermal, mechanical and electromagnetic properties of the motor.

High thrust drone motors

We have partnered with a number of leading aerospace and defense companies, including Lockheed Martin, Qinetiq, and Kongsberg.

X60 – High Power & Thrust Drone Motor

Reliable & durable multicoptor motor

Hexacopter motorThe X60 is a high-power drone motor specifically designed for industrial hexacopters and octocopters with 12S batteries, 28″ or 30″ propellers, and a maximum takeoff weight of 30 kg. The motor design incorporates a FiberPrinted slotless stator and a permanent magnet Halbach-array rotor, providing a mass- and energy-efficient solution with superior reliability and excellent peak torque and power.

ALTUS X60 Uno & Duo – Drone Propulsion Systems

Fully integrated single-rotor & coaxial UAV propulsion systems

UAV propulsion system

The ALTUS X60 Uno and Duo are highly reliable, fully integrated UAV propulsion systems that combine our X60 FiberPrinted drone motors with custom VESC-based electronic speed controllers as well as factory-balanced propellers designed in conjunction with Mejzlik Propellers. All components are specially optimized for operation in tandem with each other, ensuring the utmost in performance.

ALTUS Duo Drone propulsion system

Designed with a sealed weatherproof enclosure and able to operate at ambient temperatures of up to 40 degrees Celsius, the ALTUS X60 Uno and Duo are ideal for long-running and safety-critical UAV applications. The system design features dual-redundant UAVCAN communication lines for ensured reliability, allowing the drone to fly home even in the event of a critical error.

The ALTUS X60 Uno is designed for 20kg quadcopters and 30kg hexacopters with 12S batteries, while the coaxial ALTUS X60 Duo is designed for 30kg octocopters.
