INTERFACE OPTIMIZATION FOR HIGH FREQUENCY MOTORS

We are working in close cooperation with highly specialized partners that complement our core competences to develop more than state of the art applications with high power, high torque and high speed. To find the convincing solutions up to your requirement in shortest development time we are building bridges between these partners. For optimized interfaces between components we support:  

 

// High TCO and sustainability targets

// Improvement in power density and efficiency

// Reduction of installation space and weight

HIGH TORQUE MOTORS

  • 12 V – 800 V​ 

  • Auxiliary Motors 0,1 kW - 8 kW​ 

  • Also possible to use as small traction motors​ 

  • Traction motors > 8 kW

  • Axial flux motor design​

/ APPLICATION: e.g. Oil pump, water pump, (AC-) compressor ​ 

DOUBLE SIDED AXIAL FLUX MACHINE

  • Motor: open-slot, double-sided axial flux machine (DSAFM)
  • 12 slots and 10 poles
  • Concept: modelled and simulated using JMAG
  • Applying materials manufactured by Höganäs AB
  • Material: available in the JMAG material database
  • High strength NdFeB magnets to achieve an overload power of 7.7 kW
  • Outer diameter 109.7 mm, axial length 66.2 mm

Result: All operating points are achieved within the specification and efficiencies of over 92% are reached.
