This paper describes the experimental study of a synchronous magnetoelectric generator which magnetic system is based on the asynchronous motor: the stator of magnetoelectric generator is made up of induction machine with a number of poles pairs 2p=12, a cylindrical inductor (rotor) is composed of permanent magnets distributed on the rotor surface. The modeling of magnetic system was carried out using...
The paper considers the solution of the optimal design of the magnetic system linear magnetoelectric drive for testing visco-elastic properties of elastomers. The general approach to the optimal design of magnetoelectric drive requires taking into account the complex factors determining parameter settings that would satisfy different optimality criteria. While developing devices for analyzing the...
The paper considers the solving of the applied task of developing electric machines, particularly, designing of brushless synchronous magneto-electric machine. The need in electric machines, where the electromagnetic field excitation occurs because of using hard permanent magnets, is growing constantly which follows the creation of modern permanent magnets on the basis of neodymium alloys (NdFeB)...
The digital method of measurement and registration of dynamic loops hysteresis family of magneto-soft materials where, along with known analogues from electro-technical steel, magnetic materials with considerably smaller specific magnetic losses such as amorphous alloys on the basis of iron, is offered. Tests of magnetic properties of materials are carried out on the base of the hardware-software...

This paper provides an analytical solution to one of the main objectives within theoretical foundations of electrical engineering, formulated in particular to reflect the decision making while designing new types of synchronous generators with permanent magnets. The necessary for such generators is determined, above all, by development of the area of small-scale energy sector due to the emergence...
