Electric vehicles (EVs) are considered as a new generation of transport to solve the energy crisis. The efficiency of permanent-magnet synchronous machine (PMSM) is an important performance for the energy loss of EVs. Considering the harmonic current caused by the PWM output voltage of inverter, this paper proposes a novel global loss model of PMSM, which can calculate both fundamental loss and harmonic...
As a main driving force of electric vehicles (EVs), the loss of in-wheel permanent-magnet synchronous motor (PMSM) direct drive system can seriously affect the energy consumption of EVs. This paper proposes a loss optimization control strategy for EV in-wheel PMSM direct drive system which can optimize both the loss of PMSM and loss of inverter. The proposed method adjusts the copper loss and iron...
