MTPA and Manual Phase Angle Sweeping

Achieving maximum efficiency in Permanent Magnet Synchronous Motors (PMSMs) requires precise control of current distribution between the d-axis and q-axis. Maximum Torque Per Ampere (MTPA) ensures the highest torque output for a given current, reducing losses and improving electric vehicle range. While simulation tools provide initial estimates, Manual Phase Angle Sweeping remains essential for accurate real-world calibration—capturing temperature effects, magnetic saturation, and field weakening behavior. This process forms the backbone of reliable inverter tuning and optimal traction motor performance.
