Interior permanent magnet synchronous motors (IPMSMs) have been widely used as traction in electric vehicles. Finite element analysis is commonly to design IPMSMs but highly time-intensive. To shorten the period for IPMSMs, various surrogate models constructed predict relevant characteristics, and they optimization of IPMSM geometry. However, date, no able accurately characteristics over wide s...

This work deals with shape optimization of electric machines using isogeometric analysis. Isogeometric analysis is particularly well suited for as it allows to easily modify the geometry without remeshing domain. A 6-pole interior permanent magnet synchronous machine (IPMSM) modeled a multipatch approach and rotation realized by modeling stator rotor domain separately coupling them at interface...

This paper presents a novel non-singular fast terminal sliding mode control (NFTSMC) based on the deep flux weakening switching point tracking method in order to improve performance of permanent interior magnet synchronous motor (IPMSM) drive systems. The mathematical model (FW) is established, and calculated accurately by analyzing relationship between torque curve voltage decline curve. Next,...

The cumulative inverter losses and power consumption of a silicon insulated gate bipolar transistor (Si IGBT) three types carbide metal-oxide-semiconductor field-effect transistors (SiC MOSFETs) were evaluated on an electric motor test bench under worldwide harmonized light vehicles cycle (WLTC). SiC MOSFETs showed higher performance than Si IGBT regardless the type vehicles. In case driving in...

This paper proposes a back electromotive force estimation error compensation method for accurate rotor position estimation of surface mounted permanent magnet synchronous motors. When estimating the rotor position of surface mounted permanent magnet synchronous motor sensorless drives, a direct current offset error component occurs in the voltage sensor. As a result, the rotor position is disto...
