Rethinking the geometry of electric motion

Axial flux,
engineered differently.

Ecocipher develops yokeless, dual-rotor axial flux motors designed to deliver high torque density in a flatter, more compact architecture.

Unlike conventional radial-flux motors, where magnetic flux travels outward from the shaft, axial flux motor technology directs magnetic flux parallel to the shaft across an axial air gap.

The result is a fundamentally different motor architecture — shorter, flatter and designed for applications where torque, weight and space matter.

Axial flux vs. radial flux

Change the direction of the flux.
Change the shape of the motor.

In a conventional radial-flux motor, magnetic flux travels outward from the rotor shaft through the stator, creating a cylindrical motor architecture.

An axial-flux motor takes a different approach. Its magnetic flux travels parallel to the shaft across the air gap, creating a disc-shaped architecture with a shorter axial dimension.

This different geometry changes the relationship between torque, mass and volume — making axial flux particularly relevant where compactness and torque density are critical.

Ecocipher's motor architecture

Yokeless.
Dual-Rotor.
Single-Stator.

At the core of Ecocipher's axial flux motor technology is a yokeless, dual-rotor, single-stator architecture. Two magnet-carrying rotor assemblies sit around a central segmented stator, creating two active air gaps.

The yokeless design removes the conventional stator back iron, reducing inactive magnetic material and creating a more compact electromagnetic structure.

Dual rotor

Two magnet-carrying rotor assemblies work around the central stator.

Yokeless stator

The absence of a conventional stator yoke reduces inactive iron in the magnetic circuit.

Laminated steel cores

Laminated steel cores form part of the stator's electromagnetic structure.

Why go yokeless?

Less inactive iron.
More of the machine working.

In conventional motor designs, the stator yoke forms part of the magnetic return path.

Ecocipher's yokeless axial-flux architecture removes this conventional back iron and places the stator closer to the active air gaps.

Reduce unnecessary material and focus the electromagnetic structure around the active magnetic path.

Winding technology

Wound for precision.

Ecocipher uses segmented stator elements with concentrated windings, allowing the winding geometry to be closely aligned with the electromagnetic design.

The company is also developing automated and semi-automated winding machines to improve winding precision, repeatability and control over manufacturing.

Integration

Winding development happens alongside motor development.

Flat-wire windings

More copper in the same slot.

Ecocipher's winding approach incorporates flat-wire conductors to improve conductor utilisation within the available slot geometry.

ROUND WIREFLAT WIRE

Using the available space more effectively becomes important when designing compact electric motors for higher current density and torque requirements.

Electromagnetic design

Designed in 3D. Built through iteration.

Every motor starts as an electromagnetic problem.

Ecocipher uses 3D electromagnetic modelling to study the interaction between the rotor, stator, magnetic circuit and winding configuration before physical hardware is built.

This allows the architecture to be digitally evaluated and refined before moving into prototype development.

Thermal engineering

Power density only matters if you can manage the heat.

Higher power and torque density make thermal behaviour an important part of motor development. Ecocipher uses prototype motors to measure and understand real thermal performance, connecting simulation with physical testing.

The objective is to understand how the complete motor behaves under real operating conditions — not simply how it performs in a model.

Windings

Copper losses concentrate heat in the windings — the hottest region and the first thermal limit.

COOLERHOTTER

Illustrative heat distribution — not measured test data.

Integrated drive systems

The motor and controller should speak the same language.

Ecocipher develops motor controllers and drive electronics in-house, allowing the motor and its control system to be developed together.

Instead of pairing a motor with an external controller after development, the company considers motor characteristics and control strategy as connected parts of the same system — creating greater control over the complete electric drive system.

MOTORCONTROLLERCONTROL STRATEGYMOTOR CHARACTERISTICS
Gearbox integration

Direct drive when possible. Reduction when necessary.

Axial-flux architecture can enable applications where the motor drives the load directly, reducing the need for a reduction gearbox. For applications requiring additional torque multiplication, Ecocipher also works with cycloidal gearboxes on selected platforms.

Direct drive

Remove the gearbox where the motor can do the job — fewer parts, less mass, less loss.

Cycloidal reduction

Integrate reduction where the application demands it, on selected platforms.

The axial-flux motor platform

One architecture. Multiple power classes.

Ecocipher is developing an axial-flux motor platform across multiple output classes, maintaining the same core approach to motor topology, winding and integrated control.

The Ecocipher approach

Build the technology.
Control the stack.

From motor topology and winding systems to controllers and supporting hardware, the company develops key technologies together rather than relying entirely on independently sourced components.

This allows the technology platform to evolve as one connected system.

The future of electric motion may not need a bigger motor

It may need a better architecture.

Ecocipher is developing axial-flux motor technology around a different starting point — one where geometry, electromagnetic design, winding, electronics and application are engineered together.
