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.

The chapter aims to investigate the reduction of the fuel consumption of conventional vehicles using mild-hybridization and considering the New European Driving Cycle (NEDC), using two topologies of electrical machines dedicated to integrated starter-alternator-booster (ISAB) applications: directly connected to the crankshaft (called ‘normal ISAB’) and indirectly through the belt system (called BSAB), respectively. The behaviour of ISAB and BSAB of a hybrid electric vehicle has been investigated with a multi-domain simulation software developed in Advanced Modelling Environment for performing Simulation (AMESim).
