Electric vehicles require traction machines with a high efficiency, a high power density and a low weight. Not to forget are aspects like a fail-safe motor operation, a safe maintenance and handling and an easy and cost-effective industrial production. Based on these requirements, a 25 kW PMSM was developed as decentralized scalable drive unit for traction applications. In contrast to conventional...
The current research concerning hybrid and electric vehicles brings forward several new ideas and concepts for electric traction drives that are explicitly tailored to the requirements of the automotive sector. An alternative approach for winding design is the use of a concentrated bar winding with only one turn per coil, which reduces the effort and volume for insulation material and increases the...
