“…The required machine performance is summarized in Table II. It is shown that both the flux-weakening capability and the overload ability are imperative for EV applications [5], [8]. All three machines are required to produce continuous power of 70 kW over a speed range of 1610-4830 r/min and peak power of 140 kW for 60 s at 1028 r/min.…”

“…Compared with regular industrial machines, EV traction motors require higher efficiency, higher torque density, stronger overload capability, and much wider constant power speed range. The interior permanent-magnet (IPM) machine has been widely used in EVs due to its inherent advantages, including high torque density and wide constant power speed range [2]- [8]. Moreover, the combination of fractional-slot concentrated windings (FSCWs) with IPM machines makes it possible to possess both advantages, i.e., high power density and efficiency [9]- [11].…”

This paper mainly studies the effect of the winding layer number on the performance of interior permanent-magnet (IPM) synchronous machines equipped with fractional-slot concentrated windings (FSCWs) for electric vehicle applications. In order to quantitatively evaluate FSCW-IPM machines with different numbers of winding layers, three models with single-, double-, and four-layer winding configurations have been built to compare back electromagnetic force, average torque, torque ripple, core losses, copper losses, flux-weakening capability, overload capability, etc. Both theoretical and finite-element analysis results illustrate that multilayer windings yield lower d-axis inductance and weaker flux-weakening capability but better overload capability. It is also shown that torque ripple and core losses are significantly reduced in machines with multilayer windings.Index Terms-Electric vehicles (EVs), finite-element analysis (FEA), flux weakening, fractional slot, multilayer windings, permanent-magnet machines.

Φ Abstract --In recent years all expositions of cars show that every car manufacturing company is developing at least one electric vehicle. Recently, ITU ALEK (Istanbul Technical University Alternative Energy Club) members and its supervisor created an electric vehicle project called ITU EV (electric vehicle). This project is about developing a drive system for a conventional internal combustion engine (ICE) vehicle. The project which started in 2011, has four different main research areas. These are electric powertrain which includes water cooling design, battery part, controlling part, mechanical construction and outer design part. In this study, electric powertrain design, cooling calculations and design, and production parts of the project will be investigated. For electric drivetrain a special design of 70 kW BLDC (brushless dc) motor is produced and laboratory tests are made. The rated voltage is chosen as 355 V.Index Terms--Electrical vehicle; finite element analysis (FEA); BLDC motor; Vehicle dynamics, water cooling I.

There has been growing interest in electrical machines that reduce or eliminate rare-earth material content. Traction applications are among the key applications where reducing cost and hence reduction of rare-earth materials is a key requirement. This paper will assess the potential of different variants of flux-switching machines that either reduce or eliminate rare-earth materials in the context of traction applications. Two designs use different grades of Dysprosiumfree permanent magnets and the third design is a wound-field variant that does not include permanent magnets at all. Detailed analysis of all three designs in comparison to the required set of specifications will be presented. The key opportunities and challenges will be highlighted. The impact of the high pole-count/frequency of the flux-switching machines will also be evaluated. Experimental results for one of the designs with Dysprosium-free permanent magnets will also be presented.
