1. A system comprising:
a tone generator configured to couple to a motor gain circuit and configured to provide a characterization tone signal to the motor gain circuit, wherein the motor gain circuit is associated with a motor, and the characterization tone signal has a frequency outside of an operating frequency range of the motor;
a parameter circuit configured to:
couple to the motor to receive a set of phase current signals; and
determine a response of the motor to the characterization tone signal by separating the characterization tone signal from the set of phase current signals; and
a gain adjustment circuit coupled to the parameter circuit and configured to:
couple to the motor gain circuit;
determine a gain adjustment based on the response of the motor to the characterization tone signal; and
provide the gain adjustment to the motor gain circuit.
