E-Motor technology study and design: Patent landscape of the today EESM technology, Trend mapping analysis of the actual state of the e-Motors & Bridgeless design for an IPM motor

This thesis work has the objective to summarise six months of internship in Toyota Motor Europe. The work focus on Electric Motors for Automotive Traction and develop a landscaping analysis, a trend mapping analysis, and a bridgeless design project. In the first work a EESM patent landscaping analysis is performed, where different patents are analysed focusing on the pros and cons that the studied technology present and on the actual development of this type of motor In the trend mapping analysis rotor and stator geometries values and power and torque values are combined to perform a trending in the years about the gravimetric and volumetric power and torque density of the electric vehicles. In the last work a bridgeless design is develop considering different solutions and configurations to retain the rotor elements and to achieve better electromagnetic performance, considering the torque and the torque ripple.
