FiberPrinting™
The new way of making electric motors.
Alva’s next-gen electric motors and propulsion systems are based on patented FiberPrinting™, a ground-breaking production process enabling Alva to rapidly design and manufacture ironless windings for any electric motor or generator.
Next-generation electric motors, made in Norway
Manufacturing benefits
With FiberPrinting™, technical and composite fibers can be combined to enhance thermal, mechanical and electromagnetic properties, leaving a copper dense winding used in ironless motors
Up to 60% copper fill factor
Any pole number
Windings 90 degrees to magnetic force field
Custom series and parallel connections
Any diameter, thickness, and axial length
High-volume automatic production
Composite structure for high strength
Product benefits
Alva’s ironless motors are made up of a permanent magnet Halbach-array rotor and a FiberPrinted™ stator. The motors exhibit unique characteristics over conventional iron-cored motors due to the FiberPrinted™ ironless winding, including no magnetic stator saturation, zero cogging torque and low inductance
Extreme peak torque and peak power
Faster acceleration
Smooth motion at low speeds
Low noise and vibrations
High precision
High efficiency
Unlimited
opportunities
