The global reliance on electric vehicles (EVs) has been rapidly increasing due to the
excessive use of fossil fuels and the resultant CO2 emissions. Moreover, EVs facilitate using …

One of the main drawbacks of nonoverlapped coils in fractional slot concentrated winding
permanent magnet (PM) machines are the high eddy current losses in both rotor core and …

Electric machines with high torque density are needed in many applications, such as electric
vehicles, electric robotics, electric ships, electric aircraft, etc. and they can avoid planetary …

This paper presents a computationally efficient thermo-fluid model to predict the temperature
and flow distribution in an oil-cooled electrical machine with a segmented stator. The …

This paper presents a complete analytical model for surface-mounted permanent magnet
synchronous machines (PMSMs). A new simple and fast technique was developed to obtain …

The winding factor is an operand in order to consider the effect of winding distribution and
chording on the spatial distribution of the magnetic field in the air gap of synchronous and …

Fractional-slot concentrated-winding (FSCW) permanent magnet (PM) machines have been
widely studied in recent years. This is mainly due to the several advantages, including high …

One of the main merits offered by multiphase machines is their high fault-tolerant capability.
Literature has demonstrated that the performance of multiphase induction machines under …

This paper presents a comprehensive analysis and comparison of air-cored axial-flux
permanent-magnet machines with different types of coil configurations. Although coil factor …

This technical review evaluates advanced cooling techniques for the yokeless and
