Designing an electric motor requires a comprehensive understanding of the impacts that different
technologies can have on motor mass, performance and cost - ideally at an early stage in
the design process when design choices are still open and the cost of change is low.
" Performance Analysis of Electric Motor Technologies for an Electric Vehicle Powertrain " , is a white
paper from Motor Design Ltd, the developer of Motor-CAD multiphysics design software, that
discusses how different design choices such as motor topology, winding type and cooling system
can be compared and evaluated with the overall system impact in mind.

The first section of the paper looks at a comparison between an interior permanent magnet, induction
and wound field synchronous motor design in an EV application. The second part of the
paper takes the permanent magnet machine design and considers the trade-off between hairpin
and stranded winding technologies. Finally, three different cooling types are compared: water
jacket cooling, oil spray cooling, and combined water jacket and air cooling.
The paper explains how different motor types compare in terms of mass, cost, continuous performance,
efficiency and energy usage over typical drive cycles, and how simulation tools can be
used to quickly and easily explore trade-offs in design decisions.
