Description

Summary of the Tutorial:

This tutorial starts with a review of requirements of electric machines for two rapidly emerging areas:

  • automotive applications such as in EV traction, wheel motor, power steering, turbocharger

  • renewable energy conversion such as for conversion of wind, wave/tidal, solar thermal energies.

Recent advances in permanent magnet synchronous machine (PMSM) structures, such as SPM, Interior PM machines - radial and axial types, with distributed and fractional-slot concentrated-windings (FSCW) with a view to meeting requirements of these applications are brought out. Advantages and limitations of each type are discussed. Design and performance issues of the FSCW PM machine in gearless direct-drive applications as a motor and as a generator are also brought out. Other novel types – Flux switching, PM-assisted SyncRel, Flux-modulating PM machines are also discussed briefly. Issues relating to design/manufacturing/optimisation of PM machines for the two major types of applications and future research directions are brought out. Finally, advances in control techniques of PMSM/G – FOC, DTC, sensorless, model predictive – that are heavily dependent on the structure of a PMSM will also be covered.
