Abstract
A motor control system includes a gate driver motor controller and a microcontroller configured to generate a commutation command signal for coupling to the gate driver motor controller. The gate driver motor controller includes a current measurement circuit to measure current in each of three current paths corresponding to three motor windings, an interface to transmit a first subset of the measured currents corresponding to a first subset of the current paths, and a calibrator to calibrate a current path that is not part of the first subset of current paths when the first subset of the measured currents is transmitted. The microcontroller includes an interface to receive the first subset of measured currents and a processor to compute the current in the current path that is not part of the first subset of current paths based on the first subset of measured currents.
