The impact of sensor parameters on the accuracy of a strapdown inertial vertical gyroscope

The major factors affecting the accuracy and performance of any measuring system are the errors of embedded sensors. In this paper we analyze the impact of sensor parameters on the characteristics of an inertial vertical gyroscope based on the Wiener filter.     

Promising electromechanical energy converters based on new materials and coatings

The efficiency of new materials and the application of coatings for promising high-speed electromechanical energy converters has been estimated. A new basic model of miniturbogenerator intended for testing new materials and coatings has been developed. The experimental results obtained for pilot samples with different organic-silicate coatings show that the losses in the rotor decrease.     

Development and trends of applications of the new types of turbogenerators with vector system of field control

The results of the application of asynchronized turbogenerators with vector control and biaxial excitation in the Russian electric power system are presented. Since 2003, five air-cooled asynchronized turbogenerators with powers of 110, 160, and 320 W have been in operation at heat electric power stations. The main results of their testing and operation are given.     

Powers and speeds in electromechanical systems: Hybrid propulsion systems in cars

Mathematical expressions for determining the moments and speeds of the elements of planetary gearboxes are obtained. The possible modes of the operation of an internal combustion engine (ICE) combined with two electric machines are shown. The relation between powers of electric machines and the geometrical parameters of the planetary gear is achieved.
