NOVAMOT axial-flux motor laboratory prototype

More Than a Motor.

NOVAMOT prints the stator winding, the drive electronics and the position sensors into one multi-layer PCB — geared or direct-drive. Without hand-wound copper or bolted-on assembly.

The Idea

Four functions integrated into one board

Actuators are the largest single cost item in a humanoid robot — up to 60% of the bill of materials — and inside each one the gearbox usually costs more than everything else combined. Improving the motor or the gearbox on its own does not change that; the limit is how the actuator is built. NOVAMOT's design tools and patents enable a single printed board to perform functions that currently require four separate parts.

Printed circuit board acting as both motor stator and reduction stage, mounted on a shaft

Single-board integrationNo separate drive, gearbox, position sensor or connectors

Reduced mass and axial lengthApproximately 30% lower mass and axial length compared with a complete motor-plus-gearbox actuator.

Reduced manufacturing costs40–50% lower joint manufacturing cost — standard PCB suppliers, no winding tooling.

Operating principles

Coreless axial-flux motors for precision motion

A PCB motor is an axial-flux machine whose stator winding is printed as copper traces on a circuit board — no hand-wound wire, no iron core. Removing the core gives it exactly the properties precision robotics, gimbals and drones depend on.

Finished multi-layer PCB stator boards, copper traces forming the motor winding

The winding is printed copper on a circuit board. No hand-wound wire, and no iron core for the magnets to cog against.

Zero cogging torque

No detent steps or torque ripple — smooth, sub-degree positioning and pointing, ideal for gimbals and precision actuators.

Low phase inductance

Current rises and settles fast, enabling high control bandwidth and rapid response — paired with GaN drives switching at MHz.

Axially stackable

Stack rotors and stators on one shaft to add redundancy or scale torque — without redesigning the machine.

Products

Designed around your application requirements

Because the machine is defined in a design file rather than a winding line, torque, speed, thickness and cost are tuned to the application instead of chosen from a catalogue — and a new variant costs a redesign, not new tooling. That is what lets one platform cover compact robotic joints, gimbals and propulsion.

Working prototype

Integrated-gearbox actuator

The PCB is the motor stator & the cycloidal gear. No separate gearbox — increased torque density with reduced cost and size.

Bench-tested

Test results compared with model predictions

Torque, speed, efficiency and thermal behaviour measured on an instrumented dynamometer, then checked against what the design tools predicted.

Designed to order

Optimised for your application requirements

Electromagnetic, thermal and structural models run in-house, so torque, speed, thickness and cost are set by your envelope — geared or direct-drive.

Share your torque, speed and envelope requirements. We will assess feasibility and design the machine to meet them.

Team & Origin

The research team behind NOVAMOT

NOVAMOT was co-founded by two METU professors. The technology is rooted in METU PowerLab's decade of work on electric machines and power electronics, published in the peer-reviewed literature and protected by a national patent application and a PCT filing.

Co-founder & CTO
