ELECTRIC GENERATOR IN THE RECUPERATION SYSTEM OF THE ENERGY FROM MECHANICAL OSCILLATIONS IN VEHICLES

Abstract

The paper deals with the system of mechanical energy recuperation of vehicles in the useful electric energy accumulated in the rechargeable battery. This system creates an additional power supply on board of the vehicle and, based on the principle of energy conservation, increases the efficiency of the use of the fuel of the primary engine. One of the main elements of such system is an electric generator, which transforms the mechanical energy of the oscillations of the vehicle's chassis into electric energy. The problem of choosing and optimizing the design and parameters of the generator is considered in the paper. Given the peculiarities of the functioning of the vehicle, the most appropriate type of generator in such system is a synchronous generator with permanent magnet, which has significant structural differences from conventional synchronous machines with permanent magnets. The criterion for optimizing the generator is the largest value of the effective value of the EMF, which is induced in the stator winding. On the basis of simulation results, based on the field mathematical model, a set of values of generalized coefficients that characterize the optimal generator geometry is obtained.
