SRM

Switch Reluctance Motors (SRM) are a more budget-friendly alternative to the standard Permanent Magnet Synchronous Motors (PMSM). In addition, they also give the powertrain a significantly greener footprint, due to SRMs not using permanent magnets.

The extraction of the materials for these magnets is both labor-intensive and has a profoundly negative impact on our environment. Moreover, being independent of this rare raw material means that SRM technology is not subject to its price fluctuations on the market.

Strong and inexpensive alternative

The sound of SR motors is generally experienced as disturbing, but reducing it is often coupled with a loss of engine efficiency. Thanks to the optimized CAE design and the new algorithms that smooth out the torque ripple, Punch Powertrain´s Switch Reluctance motor is very quiet and yet generates a high power output (100 kW with 250 Nm). This engine is therefore performance orientated an inexpensive alternative to the traditionally-chosen technologies in electric powertrains.
