Ferromagnet assisted reluctance motor

Prototype motor information and goals

Motor information

  • 11 kW nominal power and 45 kW peak power
  • Has peak torque of 117 Nm and gets 45 kW already at 3700 rpm and keeps it until 7000 rpm
  • Uses 48V system for easy and safe integration to vehicles even by hobbyist
  • Uses European made components
    • Case from Kurt Maier Motor-Press GmbH
    • Motor stator and rotor from Voestalpine Automotive Components Dettingen GmbH
    • Ferromagnets from Newland magnetics
    • Motor axle, windings, end plates from Sähkö-Rantek (they will also assemble the motor for highest quality)
  • Motor geometry optimized for high torque and power production
  • Motor weight will be around 20 kg
  • Motor windings will use vacuum pressure impregnation for long life

Motor goals

  • Have very low carbon emissions from production
  • Use sustainable materials (possible with ferrite magnets)
  • Have very long lifetime 20-30 years with minimal maintenance (possible with vacuum pressure impregnation, hard anodized coating of exterior parts, with usage of high quality bearings and having discharge brushes to prevent ground problems)
  • Produce high torque and power but still be efficient at lower loads. Simulations expect over 95% efficiency even with this lower voltage and usage of ferrite magnets
  • Have easy way to install to many types of electric vehicles like motorcycles, boats and working equipment
  • Show that long lasting sustainable motors have better future than motors made cheaply in countries that don’t care about environment or sustainablity
