System, motor controller and associated method

A motor control system comprising:

• a motor;
• an input device;
• a processor coupled to said input device, said processor configured to:
• generate a command signal in response to an input supplied by said input device;
• transmit the command signal to the motor, wherein the command signal controls an operating point of the motor;
• operably connected to the motor;
• generate a response signal from the motor;
• and
• transmit a response signal from the motor to the processor;
• a current power supply;
• and
• first and second current supply lines operably connectable to said motor and said processor, at least one of said current supply lines, said input device and said processor being adapted to utilize said current supply lines both to transmit power to said motor and to transmit the command signals to said motor and the response signal from the motor over said current supply lines.

A method for controlling a motor, said method comprising:

• providing first and second current supply lines;
• operably connecting the supply lines to the motor and to a power supply;
• receiving an input at an electronic control module;
• generating, using the electronic control module, a command signal in response to the input;
• transmitting the command signal over the first and second current supply lines to the motor coupled to the electronic control module;
• generating, using the electronic control module, a response signal from the motor;
• transmitting the response signal from the motor over one of the first and second current supply lines to the processor;
• determining, from the command signal, a corresponding operating point for the motor;
• transmitting power from the power supply over the first and second current supply lines to the motor;
• and
• operating the motor at the operating point.
