Initial Evaluation of Permanent Magnet Synchronous Motor Structures for Light Electric Vehicle Applications

The current study aims to determine a viable solution for the electric propulsion system for a Light Electric Vehicle compatible with the L6e quadri-cycle constraints defined by the European Commission. System level analysis is performed to determine the performances of different topologies of the electric propulsion system, considering in-wheel electric machines or conventional structures connected to the vehicle's wheel directly or through a gearbox. The second part of the paper compares various Permanent Magnet Synchronous Machine topologies to determine the most suitable solution for the targeted application.
