“…However, the added cooling capability due to flooded machines is still not enough to guarantee an optimal electrical machine performance, especially in terms of high power, reliability, cost-effectiveness and efficiency [2]. A machine topology and configuration that guarantees a high power to mass and power to volume ratio, is a key design aspect, especially where the main constraint is the available space for the machine.…”

“…This is then usually coupled to appropriate design and optimization procedures in order to achieve a machine which gives an optimal performance for a particular application. A wealth of literature exists which investigates design and optimization strategies for PMSMs [2,5]. This paper focuses on the design and optimization of a PMSM, used to drive an oil-flooded pump for a harsh environment application.…”

The designed machine drives an electric, oil flooded pump. In order to achieve higher torque-density, a fractional slot machine (8 poles, 9 slots) with double layer (concentrated) winding has been selected after a preliminary trade-off study, which considered several slot/pole combinations and winding configurations. The developed machine provides low torque ripple and short end windings, which contribute to lower axial length and higher efficiency. The electromagnetic performances have been evaluated by using finite element method and the lamination geometry has been optimized through a genetic. The final results are presented highlighting the achieved design targets.Index Terms-PMSM, high power density machine, finite element method, Genetic Algorithm (GA) optimization.

Fault Tolerant Bio-Inspired System Controlled Modular Switched Reluctance Machine

et al. 2014

Original scientific paperFault tolerance is an obligatory feature in safety critical applications (aeronautical, aerospace, medical and military applications, power plants, etc.), where loss of life, environmental disasters, equipment destructions or unplanned downtimes must be avoided. For such applications, a novel bio-inspired motion control system is proposed. All its three components (the switched reluctance machine, the power converter and the control system) are designed to be as fault tolerant as possible. This paper describes all these three fault tolerant components: the bio-inspired control system having self-healing capabilities, the power converter with an extra leg and the fault tolerant modular machine. The theoretical expectations and simulation results are validated by means of laboratory experiments.

“…Four, five and six phase permanent magnet synchronous machines (PMSMs) have been research hotspots in recent decades [3][4][5][6][7]. The six-phase PMSM is often considered as an excellent candidate for high-performance and high fault-tolerant capability [8,9].…”

“…Also, it can be automatically fabricated so as to increase slot fill factor. What's more, alternate-teeth-wound FSCWs eliminate short-circuit faults between phases and have a relatively low mutual inductance compared with overlapped windings, which provide an insight into electrical, magnetic, thermal and physical isolation of phase windings [14]. Besides, it has been found that an improvement in the flux weakening capability of a surface-mounted PMSM can be achieved by employing FSCWs [15,16].…”

This paper deals with a fault-tolerant semi-12-phase permanent-magnet synchronous machine (PMSM) used for electric vehicles. High fault-tolerant and low toque ripple features are achieved by employing fractional slot concentrated windings (FSCWs) and open windings. Excessive magnetomotive force (MMF) harmonic components can lead to thermal demagnetization of rotor magnets as well as high core loss. An improved all-teeth-wound winding disposition that changes the winding factor of each harmonic is applied to suppress harmonics. A relatively large slot leakage inductance that limits the short-circuit current (SCC) induced in the short-circuited winding is proposed to deal with short-circuit fault. Fault-tolerant controls up to two phases open circuited are investigated in this paper based on keeping the same torque-producing MMF. The fault-tolerant control strategies corresponding to each faulty mode are studied and compared to ensure high performance operation.
