A System and Method for Reducing Torque Ripples in Electric Vehicles In an electric vehicle (10), the system includes a traction motor (250), a motor controller (200), a machine learning (SML) unit (320) and an excitation unit (340). The motor controller (200) is configured to determine a set of first rotor values (d1, q1) that includes a first magnetic flux value (id1) and a first rotor angle value (iq1). The machine learning unit (320) includes a ripple identification table (322) including a set of second rotor values for which torque ripple does not occur. The machine learning unit (320) is configured for predicting at least one time instant when a torque ripple will occur based upon a comparison between the set of first and second rotor values in the ripple identification table (322). The excitation unit (340) is configured for performing excitation at the at least one predicted time instant based upon a throttle demand and the comparison.
