Design of a Low‐Cost Permanent Synchronous Machine for Isolated Wind Conversion Systems

Abstract

The chapter deals with the theoretical analysis of two configurations of low-cost permanent synchronous generator (PMSG), suitable for small rating, direct driven applications, such as small-and microscale wind power plants. The first structure is a permanent magnet claw-pole synchronous generator (PMCPSG) to be used in an isolated microwind power plants with installed power around few hundred Watts. A permanent magnet synchronous machine with outer rotor (PMSMOR) is the second presented structure, suitable for small wind system with installed power between 2 and 5 kW. In order to obtain the optimal value of the main geometric dimensions of the generators, an optimization procedure, based on Hooke-Jeeves method, was implemented for all the considered structures.
