Performance Analysis of a Rewound Multiphase Synchronous Reluctance Machine

Predictive torque and flux control for the synchronous reluctance machine

This paper presents a predictive torque and flux control algorithm for the synchronous reluctance machine. The algorithm performs a voltage space phasor pre-selection, followed by the computation of the switching instants for the optimum switching space phasors, with the advantages of inherently constant switching frequency and time equidistant implementation on a DSP based system. The criteria...

Design and Performance Evaluation of a Medium Power Pm-assisted Reluctance Synchronous Traction Machine Using Bonded Pm-sheets

This paper describes the optimum design of a permanent-magnet-assisted reluctance rotor of a 110 kW reluctance synchronous traction machine. Previous studies show that the performance of the pure reluctance synchronous machine drive deteriorates fast in the flux-weakening speed region. To address this problem, thin bonded permanent-magnet sheet material is used inside the flux barriers of the r...

Design of a Permanent-Magnet Assisted Synchronous Reluctance Machine for a Plug-In Hybrid Electric Vehicle

In this thesis, a permanent-magnet assisted synchronous reluctance machine (PMSynRel) design is presented for a plug-in hybrid electric vehicle application. Apart from operating as a traction machine to propel the vehicle, the machine is also used when the vehicle’s battery is charged from the grid. This additional functionality puts restraints (that are discussed in the thesis) on the final ma...

Nanoactuators: Novel synchronous reluctance nanomachines

Modeling of a synchronous reluctance machine accounting for space harmonics in view of torque ripple minimization

The paper deals with modeling of synchronous reluctance motor (SynRM) accounting for all phenomena responsible for torque ripple. Based on winding function approach, the proposed model consists in computing self and mutual inductances considering no sinusoidal distribution of stator windings, slotting effect and no sinusoidal reluctance variation caused by the rotor saliency. Then, optimal curr...
