MAGNETIC FLUX SWITCHING TYPE PERMANENT MAGNET GENERATOR

The invention relates to AC electric machines with a movable magnetic flux switch and a fixed anchor with a permanent magnet and can be used as a generator, for example, for a bicycle and for powering low-power electronic devices. The technical problem solved by the present invention is to increase the specific power of the generator. The generator contains three groups of magnetic open-cores made of laminated silicon steel sheets. Each group includes two pairs of the magnetic open-cores, sections of the magnetic circuit of which contain parallel inner rods and outer rods. The magnetic flux switch is made in the form of a tape 25 made of non-magnetic material, magnetic flux toggle switches 26 made of laminated silicone steel are placed and fixed on said tape with a uniform step τz. The magnetic open-cores, connected by a plate 5a of non-magnetic material, form the first section, and connected by a plate 5b of non-magnetic material, form a second section. The permanent magnets in the first section 11a, 12a, 13a, 14a have the same polarity, and the permanent magnets in the second section 11b, 12b, 13b, 14 have the opposite polarity. Wherein, in each group, the magnetic flux in the rods 1a, 1b, 2a, 2b, 15a, 15b, 16a, 16b, 17a, 17b, 18a, 18b is directed in one direction. Gaskets 19a, 19b, 20a, 20b, 21a, 21b, 22a, 22b made of steel are placed between all the permanent magnets of the first and second sections and the surfaces of the rods. The permanent magnets of the first and second sections are connected by bridges made of laminated silicone steel 27, 28, 29, 30. The free ends of the anchor windings 6a, 6b, 23a, 23b, 24a, 24b of all three groups are interconnected according to the connection scheme of the anchor windings of a three-phase electric machine.
