Abstract :
In this article, in line with a research study, analysis and investigation of a new communication system are presented to reduce interfaces and save cables for mechatronic self-sustainable modules, which will result in new modular machine concepts. The DC link of inverter driven electrical drives is used as a communication medium for transmitting data to control the drive and to get the values of sensors installed at the motor. This article deals with analysis and modeling of disturbances and with frequency domain channel and in a second step it presents simulation results of coded orthogonal frequency division multiplex (OFDM) system operating in a realistic scenario.
