Comparison of Matrix-Torque-Component Machines with Regular IPMs for New-Energy Vehicles

New-energy vehicles (NEVs) are gaining increasing attention as global efforts focus on reducing carbon emissions and dependence on fossil fuels. The motor drive system, a core technology of electric vehicles, has become a prominent research focus in both academia and industry. This paper investigates a novel matrix-torque-component machine (MTCM) that has been proposed for use in electric vehicles in recent years. First, the paper introduces the topology and torque generation mechanism of MTCM and IPMs. For comparison, an MTCM and a detailed model of the Toyota Prius 2010 interior permanent magnet machine (IPM) are developed. The torque capacity, loss distribution, and operational performance are then compared sequentially. Results indicate that the torque-generating capacity of the MTCM is higher than that of the IPM. Additionally, the MTCM performs better in low-speed, high-torque ranges. Therefore, the MTCM shows promising application potential in electric heavy-duty trucks and as a replacement for IPMs in dual-motor architectures.
