CPC H02K 11/20 (2016.01) [H02H 7/0833 (2013.01); H02J 13/0004 (2020.01); H02K 11/33 (2016.01); H04B 3/54 (2013.01); H02K 9/19 (2013.01)] | 18 Claims |
1. A power line communications (PLC) receiver module operable to receive information over power conductors supplying a load voltage to a motor, the PLC receiver module comprising:
a sensor configured to detect electrical signals corresponding to voltage bursts imposed on one of the power conductors at a first frequency, wherein the voltage bursts comprise a message including a header and a payload having an encoded parameter value, each voltage burst detectable adjacent a positive or a negative zero-crossing of the load voltage, and wherein the header is comprised in a first pattern of voltage bursts that is not repeated within the payload to thereby enable detection of the header; and
receiver logic configured to detect the parameter value from the voltage bursts.
