Optimization Driven Motor Design - Processes and Methodology

Presentation by Lars Fredriksson, Business VP - Simulation Driven Innovation at Altair.

This presentation offers insight how Altair has approached the challenge of improving the total design balance in E-motor development. The presented study has been executed with active support of Porsche AG. The classical motor efficiency/power design problem is coupled with other physics to account for thermal effects, structural boundary conditions and vibrations. Additional effects of the inverter on the motor performance will also be evaluated by integration of both controls and physical modeling. The objective of the design optimization is to maximize torque and power under defined driving conditions. Simultaneously, rotor stresses, motor vibrations and motor temperature must be kept within certain limits.
