The breakthrough

A strategic alternative to permanent-magnet and induction motors.

The SFSM responds to the need for efficient motor technology that is less exposed to rare-earth supply chains, volatile pricing and complex high-power electronics.

01

Stator-based field coil

The field coil is moved to the stator, allowing controlled magnetisation of the salient-pole rotor without rotor windings or slip rings.

02

Optimised at partial load

Field-current adjustment supports lower current draw and strong power-factor performance over a wide operating range.

03

Simplified electronics

For synchronous operation, minimal low-power electronics manage the DC field, while conventional drives can support variable-speed applications.

Designed for manufacture

Simple materials. Scalable production. Lower lifecycle risk.

The technology uses widely available steel, copper and aluminium rather than rare-earth permanent magnets. Its pre-assembled stator components are designed to support efficient manual or robotic assembly.

  • Stable bill of materials and local sourcing potential
  • Lower rotor complexity and fewer failure modes
  • Accessible stator-side field coils for servicing
  • Cleaner recycling and refurbishment pathway
