Abstract :
In electrical drives data transmission between a motor and an inverter is required due to sensors, installed at the motor, that are used in the motor diagnostics or controlling. Generally, the data transmission is carried out using additionally installed cabling, such as, twisted pairs. In this article a new method is proposed that provides an Ethernet based communication link between the electric motor and the inverter. The method uses a motor feeder cable as a media and power line communications (PLC) as a communication method. Laboratory measurements with the method are carried out and the results of the measurements are analyzed
