Motor development and manufacturing Peter Donaldson details the many processes involved in creating new motor systems. As with any sophisticated industrial process, the development of motor systems for e-mobility is a complex and multi-stage endeavour, subject to rapid change under pressure, both to innovate and ramp up to high production volumes. The first stage is conceptualisation and definition, whereby key requirements are identified and the specifications of the motor are defined, based on the intended application, vehicle type, powertrain configuration and the regulatory standards that apply in the markets in which it will operate. Next comes design to flesh out the details of the motor geometry, including the stator, rotor, windings, housing and design software, and the subsequent electromagnetic and thermal simulations to optimise motor performance, efficiency and cooling requirements. Designs are then validated using finite element analysis (FEA) and computational fluid dynamics (CFD) simulations. Prototype development comes next, beginning with the fabrication of components such as stator and rotor assemblies, increasingly using rapid techniques such as 3D printing. Prototype motors are then assembled and put through initial bench testing to verify performance characteristics and validate simulation results. More comprehensive testing and validation follows, focused on the prototype’s performance, efficiency and durability, including dynamometer tests that evaluate torque, speed, power and efficiency under a range of operating conditions. Thermal performance testing assesses the new motor’s ability to operate reliably within the design temperature limits, while durability testing helps to evaluate its longevity and resistance to mechanical stress, vibrations and environmental factors.

Great resources in terms of interview partners! Great work, Peter!
Hey Daan Moreels, for a while I wanted to ask if we could build a vehicle model for you guys with Traxial's tech inside? Also we are interested in how you guys solve for noise especially thinking in multi-physics! Would be cool to meet your team!
Thank you for this opportunity, Peter Donaldson!
@Peter Donaldson: thank you for the comprehensive presentation of state-of-the-art development methods.
Thank you for the opportunity to talk about the development of new e-motors! Always a pleasure! ❤️
