Technical solutions are described for applying machine current limiting in permanent magnet synchronous motors. An example system includes a PMSM and a motor control system. The motor control system is configured to receive a torque command and determine whether the torque command can be satisfied based on a given voltage and a given maximum motor current limit. The motor control system is further configured to, responsive to determining that the torque command can be satisfied, determine a minimum current that satisfies the torque command. The motor control system is further configured to send the minimum current as a minimum current command to the PMSM.
