Axial flux motors have been in the focus of many research work due to their promising properties when compared conventional radial machines. permanent magnet synchronous (AFPMSM) studied literature were mostly limited surface-mounted machines (SPMSM), excluding only a few studies about axial internal (AFIPM) or magnet-assisted reluctance (AFPMaSynRM) Since numerous rotor topologies proposed and...
There is a market for small, efficient and costeffective wind generators for mini-grid and remote power systems. Direct-drive permanent magnet generators have become very attractive for this application. This paper describes the improvements achieved in an outer-rotor direct-drive permanent magnet generator by using finite element analysis and optimisation techniques. The starting torque of the...
This paper presents three novel configurations of single-phase (SP) short-stroke (SS) tubular permanent magnet oscillating machines (TPMOMs) with partitioned stator (PS), termed PS-SPSS-TPMOMs. The machine structures are described and the influence pole alignment either slot or tooth is investigated. It found that PM poles should be aligned slots in order to ease oscillation. electromagnetic pe...
In this paper a variable speed generating unit is considered, equipped with permanent magnet generator. The system analysis involves appropriate models for the generator, the static converter and the grid. Moreover, an asynchronous generator mounted on the same rotor with dump loads ensures braking actions and management of the active power produced. The modelling of the generator and power ele...
Different types of permanent magnet generators for wind power application have been subject of research during last two decades. In this thesis different topologies of electrical generators have been investigated for small scale vertical axis wind turbine application. A two stage induction generator is proposed as a alternative solution with respect to the cost of such a system. However, a bigg...
