In this paper, several aspects of high frequency related issues of modern AC motor drive systems, such as common mode voltage, shaft voltage and resultant bearing current and leakage currents, have been discussed. Conducted emission is a major problem in modern motor drives that produce undesirable effects on electronic devices. In modern power electronic systems, increasing power density and d...

In the article, mechanical and electromechanical starting characteristics of an asynchronous electric drive a two-piston ship compressor are investigated by numerical method. A distinctive feature operation reciprocating is that its load torque changes with certain frequency. The dependence on shaft piston angle rotation presented in form Fourier series. Moments inertia reduced to single system...

This paper presents experimental analysis of wheeled mobile robots. Mathematical modelling of the mobile robot is presented. The mobile robots consist of an omni-directional and three differential drive mobile robots are tested and moved in given trajectories and the systematic errors of the robots are determined. A new method for omni-direction mobile robot was introduced in which the robot wa...

This paper presents characteristics and solutions to some practical problems concerning the new digital Generalized Indirect Multispeed Method (GIMSM), for measurement of transient electrical and shaft torques occurring in a complex serial multimachine AC drive system. The method indirectly includes torsion and internal machine and shaft damping. It is based on the measurement of the transient ...

As the main drive components of the automobile transmission, the performance of gear shaft plays an important role on transmission performance. Aiming at the existing problems of the traditional strength check method of gear shaft, the objective of this study is to take a five-speed transmission as an example, to accomplish the strength analysis of gear shaft of the automobile transmission base...
