Abstract

This article has reported on an industrial R&D project aimed at identifying a cost-effective response to the more and more challenging high-speed motor requirements that presently come from the gas industry sector. To meet the very high efficiency, dynamic performance, and reliability standards required by cutting-edge turbomachinery drive applications, a special PM synchronous motor prototype has been developed. The identified technology includes AMBs for rotor levitation, a slotless stator design, and a Halbach-array PM rotor. Motor design optimization through genetic algorithms has been presented as a tool to search for the best tradeoff between performance targets and industrial production cost reduction. Extensive prototype testing under converter supply has been reported as a successful validation of the selected technology.

Abstract

Gli attuatori oleodinamici usati per timonerie e pinne stabilizzatrici sviluppano elevate coppie a basse velocità. Viene presentato, in alternativa, un innovativo motore elettrico lineare ad elevata spinta alimentato da inverter per azionamenti diretti a bordo nave, che offre grandi vantaggi in termini di compattezza, manutenzione, efficienza, e tolleranza al guasto.

Abstract

Permanent-Magnet Synchronous Linear Motors (PMSLM) are more and more frequently used as all-electric direct-drive actuators in those applications where a force needs to be developed along a fixed direction. In this paper, an accurate 3D thermal model of a PMSLM is derived through a lumped-parameter network approach which exploits all the symmetries in the actuator structure to maximize the spatial density of nodes. Numerically-efficient techniques are then proposed to solve the thermal network analytically. Some experimental validations are finally presented based on the thermal testing of a laboratory prototype.
