Flux switching alternators for small wind generation

Abstract

Abstract. This paper considers the application of flux switching alternators for small wind generation. First, after a brief presentation of the small wind energy systems, a description and the fundamentals of flux switching machines is given, then the state of art of flux switching generators is presented. Finally a critical assessment is shown, considering the main advantages and drawbacks of this type of machines as alternator for use in small wind generation systems. . Key wordsSmall wind power generation, alternators for wind energy, flux switching machines.

Magnetic Flux Switching Type Permanent Magnet Generator for Bicycles: Modelling and an Experimental Study

“…Flux switching machines have a number of properties that allow them to be used for converting mechanical energy into electrical energy in devices where the armature winding with a fixed permanent magnet can be located radially or axially relative to the movable magnetic flux switch [10]- [12]. In this case, a mechanical drive can perform rotational or cyclic movement relative to the stationary part and, in the view of the authors, could be used as an alternator for bicycles.…”

Axial Flux Switching Permanent Magnet Alternator with External Magnetic Cores

“…This type of machines has been first considered by Rauch and Johnson [5], and can be viewed as an evolution of an inductor generator. The articles [6]- [9] present the results of studies of magnetic flux switching machines by a number of authors.…”

Design Optimisation and Performance Evaluation of Flux Switching Machines for Geared Medium-Speed Wind Generator Drives

“…Moreover, in Sulaiman, Kosaka and Matsui (2012) [95], a different structured WF-FSM was designed and evaluated for maximum torque/power capabilities relevant to automotive applications. No doubt, the candidacy of FSMs for wind energy application is mounting as supported in an assessment study by Andrada and Martinez (2016) [120], however only a handful of researchers have attempted using non-rare-earth-PM field excitation sources as done in Wang et al (2013) [81] and Ojeda et al (2012) [37] for LS drivetrains. Geared MS drivetrains are important because they reduce the gear box size to 1-or 2-stage from 3-stage or even more.…”
