A Synchronous Reluctance Motor Solution for Electric Vehicles Traction
摘要
The paper presents a high speed 200 kW synchronous reluctance (SynR) motor for a full electric vehicle. It is a low-cost magnet-free motor, also suitable for mass production and able to reach good performance and meet the demanding requirements typical of an electric car. An innovative asymmetric rotor with “fluid-shaped” barriers has been designed with multiple ribs that connect the rotor segments to each other axially and transversally. The motor performance has been evaluated over the full speed range by a finite element tool and for the Worldwide Light Vehicles Test Procedure (WLTP) Class 3 driving cycle.
