Abstract :
A feedback loop is used in the motor speed control in order to transmit the measured motor rotational speed information to the controller. The implementation of the feedback loop requires cabling between the motor and the frequency converter both for signalling and powering. However, the motor power cables could be also used for data transmission. The possibility of using the same motor feeder cable for supplying power to the motor and for transferring the motor rotational speed information to the controller is researched in this article. The data transmission utilizes a PLC (power line communication) method that forms an Ethernet connection over the motor feeder cable
