Abstract
This disclosure describes a system for sending control signals and receiving sensor signals over cables at long distances. Electric currents and signals traveling down long cables can undergo phenomenon that are not present in relatively short cables. Therefore, this disclosure contemplates solutions for overcoming or compensating for these phenomenon to enable control of an electric machine using long cables. The solutions can include a signal conditioning circuit, configured to output a DC current corresponding to the sensed voltage associated with the sensor, a first conductor, that transmits the DC current from the signal conditioning circuit to the controller, and a signal generator, configured to receive the command signals and generate pulse width modulated (PWM) actuating signals based on the command signals.
