HDSRM: A Magnet free motor with no compromise

No Rare Earth Magnets

lower cost, improved sustainability and reduced supply risk compared to permanent magnet (PM) motors 

High Temperature Operation

no magnets means no risk of demagnetisation, enabling shared coolant loop with ICE engine 

Efficient where it Counts

design optimised to be more efficient than a PM or induction motor at normal commercial vehicle operating points 

Robust and Reliable

no magnets or rotor bars means inherently fewer failure modes 

Off-the-Shelf Power Electronics

unlike conventional SRMs, HDSRM runs with any suitable, commercially available 3 phase inverter 

Low Noise and Torque Ripple

HDSRM’s unique architecture means low noise and torque ripple, overcoming SRMs’ key weaknesses
