This paper studies the spatial distribution laws of rotor deformation of interior permanent magnet synchronous motors (IPMSMs) with V-shaped rotor structures. The structural-electromagnetic finite element models of IPMSMs with deformed and undeformed rotors are developed to investigate the effect of different rotor deformation types on the magnetic radial forces at no-load and on-load conditions....
This article proposes an energy recuperation management of a Hybrid Energy Storage System (HESS) during regenerative braking of an Electric Vehicle. The HESS is composed of a Li-Ion battery, and a high speed Flywheel Energy Storage (FES). At low speed, the integration of a controlled dissipative resistor is used to prevent battery overcurrent and overvoltage. At high speed, Voltage Current Limited...
In a single-phase to three-phase inverter that does not have an inductor or electrolytic capacitor, the inverter must control not only the motor but also the input power factor because there is no power factor correction circuit or energy buffer. To improve the input power factor, several control methods are proposed. However, if the motor has large spatial harmonics caused by the rotor structure,...
In recent years, Interior Permanent Magnet Synchronous Machines (IPMSMs) have attracted a considerable attention in the scientific community and industry for Electric and Hybrid Electric Vehicle (HEV) propulsion systems. Look-up Table (LUT) based Field Oriented Control (FOC) strategies are widely used for IPMSM torque control. However, LUTs strongly depend on machine parameters. Deviations of these...
