The analysis of existing alternative power source equipment that convert other types of energy into electric power was carried out. This study proposed a technical solution for the design of the power generating tile or step, which converts the kinetic energy of press into electric power and accumulates it. The operating principle of the power-generating tile is described as an alternative, decentralized source of electrical energy. The experimental research of the developed device was conducted and the method of conversion of kinetic energy into electric power improved. A correlation method that allows conducting analysis and calculation by quantitative indicators of the generated electricity from press was presented. The proposed device can be used as an alternative source of electricity in places with great foot traffic. The device has small overall dimensions and can easily be set up in various types of aisles, stairs, and integrated into the network of LED lighting.

The aim of the study is to create a method for selecting an asynchronous traction electric drive for an electric vehicle that enable the assessment of necessary technical, environmental and operational qualities. When choosing an electric motor for a traction electric drive, the methods for calculating electric machines, reducing the vibrations and electric drive theory were used. The economic and environmental characteristics of the car was analyzed and the use of a traction drive was deemed an effective solution to this problem. The analysis of advantages and disadvantages in traction electric drive were assessed and it was proved that an asynchronous frequency-controlled electric motor is well suited for a traction electric drive. This facilitates the minimization of the size and weight of the entire vehicle. To improve the reliability and service life of electric motors operating in automobiles with high rotational frequencies, a proposal to evaluate the quality of traction electric motors by the level of vibration in the frequency range of 5-10,000 Hz was made. For this study, three classes of vibration norms are offered and the means to achieve them are examined and the recommendations not to exceed them in electric and hybrid vehicles were determined.
