Investigation of the Maximum Torque-per-Ampere Control Algorithm for Permanent-Magnet Synchronous Generators
摘要
The Maximum Torque Per Ampere control strategy is widely applied in interior permanent magnet synchronous machines to optimize current utilization and improve drive system efficiency. By calculating the optimal Id and Iq current components for a given torque demand, MTPA minimizes the stator current magnitude, thereby reducing copper losses and thermal stress. This method is particularly effective under low- and mid-load conditions and serves as a key technique for high performance vector control in electric machines.
