01
Machine
A salient pole synchronous machine drawing on multiple excitation sources — ferrite, wound field, armature — with rotor geometry engineered for reluctance torque.
Product
The Universal Synchronous Motor Drive.
The product is not a motor. It is a drive: machine, power converter, energy source, motor and converter control, and energy management, designed as one system. Splitting those into separate purchases is how the industry arrived at designs that only work with rare earth magnets. Designing them together is how you get out.
One system, five elements
02
Power converter
Sized and topologically matched to the machine it drives, including the field supply, rather than selected off a catalog after the fact.
03
Energy source
The battery or supply is part of the design envelope. Field energy, drive efficiency and source characteristics are traded against each other explicitly.
04
Motor and converter control
Coordinated current allocation across excitation sources: estimation, allocation and fault handling, with the same control structure carried across power levels.
05
Energy management
Field strengthening and weakening on command, shaping the efficiency map to the mission rather than accepting the map a magnet fixes at design time.
What the architecture buys you
Permanent magnet class performance, without the permanent magnet supply chain.
- Performance without exposure. The design target is 85–95% of the torque density of an equivalent NdFeB machine using only widely available materials — a modelled target, stated as such, not a measured result.
- A field you can command. Wound field excitation strengthens or weakens on demand, extending the efficient operating envelope instead of fighting a fixed magnet with stator current.
- Demagnetization immunity. An electromagnet cannot be permanently demagnetized by fault currents or thermal excursions. A magnet can.
- Stable, multi-sourced materials. Ferrite, copper and iron, from many suppliers on several continents, at prices that do not move with export policy.
Applications
One architecture, instantiated per domain.
Small aerial platforms
Weight-critical propulsion and actuation where supply certainty matters as much as power density.
Mobility and traction
Traction drives that hold their performance class while removing the most concentrated link in the bill of materials.
Industrial and precision actuation
Servo and actuation systems with controllable excitation, demagnetization immunity and stable material costs.
Assistive and wearable systems
Compact, quiet, efficient drives for devices that move with people.
Where the program stands
The architecture and its control formulation are defined; performance figures on this site are modelled targets and are labelled as such. We are engaging early partners in each application domain now. If your system depends on a magnet supply chain you do not control, we would like to talk.
