Abstract
Technical solutions are described for power management in permanent magnet synchronous machines. An example system includes a permanent magnet synchronous motor (PMSM), and a motor control system that limits supply current and regenerative current of the PMSM. The limiting includes receiving a torque command and generating a corresponding current command for generating an amount of torque based on the torque command. Further, the limiting includes determining an estimated battery current that is drawn corresponding to the current command. Further, in response to the estimated battery current exceeding a threshold, a modified torque command is generated, and a modified current command corresponding to the modified torque command is also generated. The modified current command is used to cause the PMSM to generate the amount of torque.
