Examining ways to Maximizing Power Density in Electric Machines for Traction and Power Generation in Hybrid Electric Vehicles In every electrification program, traction motor efficiency is paramount. Efficiency of electrical energy use is usually what is most discussed; however, there is another form of efficiency that is quite important: power density. This efficiency is carried out by maximizing performance and minimizing volume and weight. There are many aspects that impact power density. This presentation will investigate what the main drivers of power density. Designers will learn how voltage and/or current, cooling, winding selection and rotor speed can all impact electric motor performance. If the vehicle designer understands how these relate to one another and the impact they have on electric motor/generator performance, one can optimize and select the rest of the components in the powertrain to maximize power densities to reduce costs.
