The electric excitation and the parameter excitation from mesh stiffness fluctuation are analyzed. The forced response equations of the drive system to the coupled excitations are presented. For the exciting frequencies far from and near natural frequencies, the forced responses of the drive system to the coupled excitations are investigated. Results show that the nonlinear forced responses of ...

This paper is devoted to the disclosure of opportunities for development an electric drive control system based on frequency converters manufactured by Schneider Electric. The contains results practical experience in manufacture hardware, parameterization and programming system. As a object, bridge crane with main hoist, auxiliary hoist carriage movement mechanisms considered. was developed ass...

The paper presents a number of advanced solutions on electric machines and machine-based systems for the powertrain of electric vehicles (EVs). Two types of systems are considered, namely the drive systems designated to the EV propulsion and the power split devices utilized in the popular series-parallel hybrid electric vehicle architecture. After reviewing the main requirements for the electri...
