LV14695A - Inductor generator for bicycles - Google Patents

Abstract

The invention relates to the field of electrical engineering, particularly, to the electric AC machines with a rotating distributor of magnetic flux, with a static armature and a magnet. The aim of the invention is to raise the specific power of an electric AC machine, more particularly of an inductor generator for bicycles. The generator (Fig. 3) contains a commutator of magnetic flux executed in the form of disk 1 connected with a bicycle wheel, while slots 2 of said disk 1 comprise magneto-conducting plates 3 evenly spaced with step Tz on the periphery of circumference, and the inductor with magnet 4, winding 5 and two stationary magnetic cores, each of them having two pairs of bars 6 to 9 and 10 to 13 located on the opposite sides of disk 1 in parallel to its rotation axis, with teeth 14 on the ends of the bars 6 to 9 and 10 to13 of the first and the second magnetic core and the magneto-conducting plates 3 having width lz in the radial direction and separated by airgaps delta1 and delta2. The inductor is additionally provided with winding 15 and magnet 16. The bars 6 to 9 and 10 to 13 form two ...-wise cores 17, 18 and 19, 20, between which magnets 4 and 16 are placed, while in the slots of cores the 17,18 and 19 , 20 the windings 5 and 15 are dropped, each of them wrapping the magnet and two bars adjacent to it, with both the magnets 5 and 15 in the magnetic circuit of the inductor being series-connected. The teeth 14 on the neighbouring bars 6 to 9 and 10 to13 in the first and the second magnetic core of the inductor are separated along the circumference by distance tau1 determined by the relationship:..........while the teeth 14 on the bars adjacent to the magnets 5 and 15 are separated along the circumference by distance tau2 which is determined by the relationship:............where k1 and k2 are integers equal to 1, 2, 3, 4, ..., n. The teeth 14, on each of the bars 6 to 9 and 10 to 13 are executed with even step tauz along the circumference. The disk 1, in the slots 2 of which the plates 3 of the magnetic flux commutator are arranged, is made of dielectric non-magnetic material. The magneto-conducting plates 3 of the magnetic flux commutator are executed in the form of a hexahedron.
