摘要： A motor control system is provided, and includes a motor, at least one differential amplifier configured to monitor phase current applied to the motor, and a current compensation controller. The current compensation controller is in communication with the at least one differential amplifier, and is configured to periodically determine a common-mode voltage of the at least one differential amplifier. The current compensation controller is also configured to determine a corrected phase current value based on the common mode voltage.
