Multiphase Permanent-Magnet Motors are an attractive alternative to induction machines for a variety of applications owing to their reliability and dynamic performance, suited for emerging applications such as automotive or traction systems. In this context, diagnosing the status of the motor magnets is crucial for improving the reliability of the machines. This paper is focused on the demagnetization...
Permanent Magnet Synchronous Motor (PMSM) is an attractive alternative to induction machines for a variety of applications mainly because of their reliability and higher dynamic performances, adapted for emerging applications such as automotive or traction systems. In this context, diagnosing the magnets status of the motor is crucial for improving its reliability. This paper presents a new characterization...
The main topic of this paper is the combination of two different technologies, i.e. the technology of tubular permanent magnet (PM) actuators, and the technology of multiphase drives. An electric drive consisting of two five-phase PM tubular actuators fed by a single five-phase inverter is described. The control scheme of the drive for position control is presented and the performance of the drive...
Nowadays Permanent Magnet Synchronous Motor (PMSM) are an attractive alternative to induction machines for a variety of applications due to their higher efficiency, power density and wide constant power speed range. In this context the condition monitoring of magnets status is receiving more and more attention since is critical for industrial applications. This paper presents a characterization of...
In this paper an optimal disturbance-free control strategy suitable for open-phase fault operation of multi-phase current regulated motor drives, is presented and tested. The proposed strategy, which is based on the multiple space vector representation of multi-phase systems, minimizes the stator copper losses either in transient or steady-state operating conditions. The effectiveness of the proposed...
