The Customer is a motorbike manufacturer of both conventional and electrical variants.

Why APA?

APA team is highly experienced in designing and simulating electrical machines and has wealth of knowledge in magnetism, electric machines design and thermal design of electric motors.


The scope is to design an electric axial flux motor for a competition motorbike application using Simulation technologies.

Design Challenges Involved:

  • ● Compact motor with high power density
  • ● Very high efficiency in order to maximize the battery range
  • ● Low torque ripple

Design Process:

  • ● Pre-sizing of the machine using Analytic software
  • ● Performing Finite element simulation in order to compute magnetic saturation, torque, current, gamma angle for the rated conditions
  • ● Simulating Coupled magnetic & thermal effects in order to have into account the cooling of the machine
  • ● Additional finite element simulations to plot the efficiency map for various Torque-speed combinations
  • ● Optimization to reduce torque ripple
  • ● Thermal simulations in order to get the temperatures distribution
  • Value Delivered:

    • ● Reduced the number of prototypes and hence the cost
    • ● Reduced “the time to market” by adopting the simulation driven design approach
