1. A motor control feedback and adaptation system with drive-sense circuit (DSC), the system comprising:
a motor controller operably coupled to a motor and configured to provide a motor drive signal to the motor to facilitate operation of the motor;
a drive-sense circuit (DSC) operably coupled via a single line to a coupling between the motor controller and the motor and configured to:
generate a DSC signal based on a reference signal;
provide the DSC signal via the single line and simultaneously to sense the DSC signal via the single line;
based on the sensing of the DSC signal via the single line, detect a change of the DSC signal corresponding to an effect on the motor drive signal that is based on an electrical characteristic of the motor; and
generate a digital signal representative of the electrical characteristic of the motor;
memory that stores operational instructions; and
one or more processing modules operably coupled to the motor controller and the memory and configured to execute the operational instructions to:
receive the digital signal representative of the electrical characteristic of the motor;
process the digital signal to determine information regarding one or more operational conditions of the motor; and
based on the information regarding the one or more operational conditions of the motor, selectively facilitate adaptation of the motor drive signal to modify operation of the motor via the motor controller.
